  • How electrified trailers are changing truck stability: a system simulation study

    Introduction Electrification is rapidly reshaping the commercial trucking industry, promising cleaner and more efficient transport solutions. Driven by new regulations [ 1 ], the electrification of heavy-duty vehicles (HDVs) and their trailers represents is essential to decarbonize freight logistics [ 2 ]. One emerging innovation is the electrified drive axle, or e-axle, integrated into heavy-duty vehicles (HDVs) and their trailers to provide regenerative braking and additional traction. But introducing this technology fundamentally alters the dynamic characteristics of the entire vehicle, bringing new challenges in vehicle stability, a critical safety aspect for heavy-duty trucks. Our recent simulation-based study dives deep into these challenges, analyzing how electrified trailers interact with existing vehicle control systems like ABS and ESP. The goal: to identify potential stability risks including jackknifing, shaking, and roll-over [ 3 ], and uncover how a smart supervisory control system could help ensure safe operation across all driving conditions. Methodology To investigate the complex dynamics of an e-trailer system, a detailed multi-body simulation model was developed using Simcenter Amesim . Simcenter Amesim is a powerful platform for multi-domain system simulation, enabling the modeling of mechanical, hydraulic, pneumatic, thermal, and electrical components within a single environment. 2.1 Vehicle Model Description The simulated vehicle configuration consists of a 3-axle articulated vehicle: a 2-axle tractor unit coupled with a 1-axle semi-trailer featuring an electrified drive axle. The multi-body template model VDCAR22DOF01 was employed, which is specifically designed to account for critical stability issues in articulated vehicles, including: Jackknife: The acute angle formed between the tractor and trailer. Shaking: High-frequency oscillations of the vehicle body. (Trailer swing) Roll-over: Lateral instability leading to vehicle overturning. Standard tractor and semi-trailer combination Tractor and semi-trailer combination with driven trailer electrical axles 2.2 Control Systems The model incorporates realistic chassis stability controllers for both the tractor and the trailer: Tractor Unit: Equipped with ABS (Anti-lock Braking System) and ESP (Electronic Stability Program) [ 4 ]. Trailer Unit: Equipped with ABS and TCU (Traction Control Unit). The e-axle’s regenerative braking and electrical traction capabilities are integrated with specific blending strategies. The interactions between these e-axle controls and the conventional chassis stability controllers are a central focus of the analysis. Simcenter Amesim model sketch Traction blending “parallel” strategy (e-trailer machine vs. truck engine) 2.3 Driver Model An advanced driver model, utilizing Model Predictive Control (MPC) techniques, was implemented. This robust control strategy ensures accurate path following and effective sway control of the trailer, providing a realistic representation of driver inputs during various maneuvers. 2.4 Test Track Definition The simulations were conducted on a virtual test track based on a real-world road section in Croix-Rousse, Lyon, France. This challenging route includes significant ascending and descending slopes, which are crucial for evaluating the e-axle’s performance during regenerative braking and traction phases. The varying gradients and curves allow for the assessment of vehicle stability under diverse load conditions and driving scenarios. Selection of the road path with the Route planning Tool, used in the Track Import Tool Visualization of the road track Results and Discussion The Simcenter Amesim simulations provided comprehensive data on electric machine performance, battery state of charge (SOC), and overall vehicle dynamics. Electric Machine Torque at trailer axle, and battery State Of Charge (SOC) 3.1 Electric Machine Performance and Battery SOC During the ascending sections of the test track (e.g., 0-150 seconds), the e-axle required significant traction torque to assist the tractor. Conversely, during important descending sections (e.g., 250-300 seconds), the e-axle effectively engaged in regenerative braking, leading to a notable increase in the battery’s SOC. This demonstrates the e-trailer’s potential for energy efficiency and reduced reliance on friction brakes. Rapid torque sign switches (from traction to regeneration) were observed before and after overcoming road cornering, indicating dynamic operation of the e-axle. 3.2 Vehicle Dynamics and Pathological Situations The simulations revealed several critical “pathological” situations that underscore the stability challenges introduced by e-axles. One such instance occurred during a combination of significant driver steering input and braking action, where a trailer wheel was observed to be on the verge of losing contact with the road. This scenario, if unmanaged, could lead to a roll-over event. A crucial observation pertained to the interaction between the electric machine controls and the chassis stability controllers. In certain cases, particularly during rapid torque switches or intense braking/traction demands, the individual actions of the ESP on the tractor unit, ABS on the trailer, and the e-axle’s torque control were not harmonized. The absence of a high-level supervisory control system to coordinate these conjoint actions was identified as a significant risk factor. Without such a supervisor, the study indicated that a complete instability of the truck + trailer vehicle could foreseeably occur at higher velocities, highlighting a critical safety concern. Trajectory, target velocity and steering angle 3.3 Implications for Control Strategy Development The findings emphasize that simply integrating an e-axle with independent control strategies for regenerative braking and traction is insufficient. Effective integration requires a sophisticated, higher-level supervisor that can intelligently blend the e-axle’s operations with the conventional chassis stability controllers. This supervisor would need to dynamically adjust torque distribution, braking effort, and traction forces across all axles to maintain overall vehicle stability under varying road conditions, driver inputs, and e-axle operational modes. Chassis controller status (ESP and ABS) Conclusion The findings from this study highlight a key takeaway: electrified trailers hold great promise, but they require sophisticated coordination between new and legacy control systems to keep trucks stable and safe. A high-level supervisory control system is essential to avoid dangerous scenarios such as wheel lift and rollover, especially at highway speeds. If you’re involved in vehicle design, control system development, or fleet safety management, this research offers valuable insights to guide your work.

  • What’s new in Simcenter FLOEFD 2512? | CAD-embedded CFD simulation

    The new Simcenter FLOEFD 2512 software release as of December 12, 2025 is now available in all its CAD-embedded CFD variants, and also the Simcenter 3D embedded variant. This release delivers focused improvements for fast sealing of geometry for internal flow analyses for all general purpose CFD applications through to multiple enhancements for electronics thermal analysis workflows. Please read on below to explore every new feature grouped under key Simcenter pillars, or scan the topic list on the left hand side to shortcut to the sections that interest you most. Auto-sealing of CAD geometry for internal flow CFD analysis There are many reasons for performing internal flow CFD simulations depending on modeling application or computational efficiency. For any internal flow scenario, you want to seal geometry as quickly and efficiently as possible For complex CAD assemblies with hundreds or thousands of parts, this can become a time consuming challenge to make the geometry watertight. You spend your time first, locating gaps and openings, and then sealing them manually with geometry. Such approaches also mean you are making modifications or additions to the CAD model that need to be tracked and removed before you hand back modified product geometry to design and manufacturing teams after you finish your analysis tasks. CFD tools typically have features or utilities to help you. Simcenter FLOEFD users will be familiar with Simcenter FLOEFD’s existing automatic fluid volume recognition strengths and tools such as “leak tracking” to identify paths between faces which is helpful in many instances. In Simcenter FLOEFD 2512 , a step change in auto-sealing for internal flow CFD tasks has been delivered to engineers in the form of enhancements to “Close Thin Slots” and “Fill Thin Slots”. This feature is accessible when you are utilizing Mesh Boolean approach to geometry handling and meshing, that is particularly suited to complex assemblies and varying quality found in CAD models. You can now retrieve the internal fluid region automatically for non-watertight models more easily, efficiently, and without altering CAD geometry. How do you control this new automatic mesh-enabled sealing ? Users configure “Fill Thin Slots” approach in 2 ways starting from the ribbon bar: Within the mesh group, select either global mesh or local mesh and then in mesh settings you activate close “Close Thin Slots”  then specify the “Maximum Heigh of Slots to Close” and other parameters.ers. Within the Insert group, select Source> Fill Thin Slots which opens a dialog. You then select in the graphic area faces on either side of the slot, or choose relevant bodies to consider their faces Set Solid material set the desired material (or allow the default setting). Set the parameter for “Maximum Heigh of Slots to Close” Choose between options: Fill Thin Slots only ( A conservative approach where solid material is applied within the slot) Fill within slots and openings (A default approach that is a more comprehensive sealing approach where solid material is applied in the slot and also extends into the fluid domain by one computational mesh cell to seal the opening fully) Additional notes: Simcenter FLOEFD chooses material properties from nearby to the gap to preserve close thermal model accuracy, or alternatively users can set a default value. There is an option in the mesh viewer to view where where cells are inserted by selecting a mesh plot of “closed thin cells”. How do you seal thin gaps in assemblies to prepare CAD geometry for CFD internal flow studies? Find out about the new approach in Simcenter FLOEFD 2512 by watching this short video on how seal an automotive lighting CFD model for thermal analysis where there are many gaps to seal in the CAD assembly for an internal flow case. The approach uses the method starting from the “Fill Thin Slots” dialog opened from the insert group Sources>Fill Thin Slots in the ribbon. It also shows how you can view where solid material cells are added using using the mesh viewer. Faster BCI-ROM extraction: Setting specific HTC ranges A new way to set specific heat transfer coefficient (HTC) ranges has significantly shortened the reduced order model extraction time for BCI-ROM models. Below are results comparisons for one example model where setting suitable ranges of HTC for each boundary condition is compared to setting a single common range value. In this case, extraction is 8 times faster and memory peak usage was more than halved. Shorter solve time for your models with thousands of two-resistor (2R) or Network Assembly components Thermal engineers frequently leverage components modeled as two-resistors (2R) or Network Assemblies in their models. Calculations for models with hundreds or even thousands of these is now much faster through software optimization implemented in Simcenter FLOEFD 2512 release. This enables the preparation stage of analysis to take significantly less time and use less memory. A Simcenter FLOEFD model containing DIMM memory card assemblies on a motherboard with components modeled as two-resistor (2R) type components. Download Simcenter FLOEFD 2512 and evaluate your own models with 2R and Network Assembly components to see what kind of speed you can get. For one example model, containing many 2R components, a comparison was carried out with the results shown below. A speed-up by a factor of 6 was realized for the solver time compared to the prior 2506 release and a significant reduction in peak memory usage achieved by a factor of more than 3 and a half. A useful update to scripting in EDA Bridge for PCB data processing To reduce time correcting script errors that are typically only discovered at runtime when transferring from EDA Bridge to Simcenter FLOEFD that force project restarts, scripts are now validated before running to catch errors and prevent disruption. Reduced order modeling: BCI-ROM support for 2R and Network Assembly components Boundary Condition Independent-Reduced Order Models are reduced order models that operate in any thermal environment and are extracted from a 3D conduction-only model in Simcenter FLOEFD . It is now possible to extract these from 3D electronics thermal analysis models that contain 2R and Network Assembly components. As a recap on BCI-ROM model formats that you can generate in Simcenter FLOEFD : – matrices (for standalone solution) – FMU format (for system simulation use in accordance with FMI standard) – VHDL-AMS format (for circuit simulation electro-thermal modeling use) Accurate radiation modeling: Henyey-Greenstein phase function Simcenter FLOEFD has a proven history of radiation modeling for lighting applications. In the Simcenter FLOEFD 2512 release, the Henyey-Greenstein phase function has been added that enhances accuracy for modeling scattering in certain semi-transparent materials. (This is accessible via the Simcenter FLOEFD Lighting module) You select this option and define scattering coefficients in the item properties menu. A simple comparison using basic model and source and then changing the scattering coefficient value of a plexiglass material illustrates scattering below. Easier sub model re-use: Rebuild of sub-projects “From component” Many Simcenter FLOEFD users work with sub models. The previous 2506 release delivered capabilities to define project parameters in sub projects so they propagate upward into your main CFD model. Building on that release and efforts to deliver more library driven re-use of components and sub projects, in the new 2512 release there is now a built-in function to select rebuild of all sub-projects at the same time when this is required. This eliminates time overhead of manual rebuild of each sub project. View tabular results: maximum temperature column in Component Explorer If you are working with a complex thermal model and want to more quickly retrieve maximum temperatures of all components you can now do so in Component Explorer (as a convenient alternative to assigning many Volume Goals) . A new column provides maximum temperatures of all solids with minimal effort and does not slow down the solver. You can also export value to Microsoft Excel. You can also export a useful matching table of component names, input data and resulting maximum temperatures automatically leveraging Batch Results Processing. As a reminder, Component Explorer received significant updates in the 2412 release (LED and 2R model creation, surface power listing/summation and more) and 2506 (status and temperature column) release, so please do go back and review prior release blogs and documentation. Updated FMU graphical editor makes connections clearer Users are starting to leverage multiple FMU based components in their Simcenter FLOEFD projects more and more since the introduction of “FMU as a feature“. To aid the understanding of the connections to the project and to connect multiple FMU’s to each other more easily, an FMU graphical editor has been introduced. You can more easily map goals to inputs and interpret connectivity between FMUs as complexity increases. Automation in Simcenter FLOEFD 2512: Added new capabilities in EFDAPI Automation of simulation tasks continues to be a popular topic with users. EFDAPI, the API introduced back in  Simcenter FLOEFD 2312 , continues to be developed based on consistently received user feedback. Key new EFDAPI capabilities added in Simcenter FLOEFD 2512 : Switch geometry recognition to Mesh Boolean Apply default radiation surface Switch between Global and Face coordinate systems For NX users performing PCB thermal analysis: PCB Exchange – EDA Bridge integration update For customers using Xpedition and NX CAD software, there are linkages for close MCAD-ECAD collaboration enabled by PCB Exchange.  As of this release, you can now author the set up of a PCB thermal simulation for Simcenter FLOEFD for NX , right from within the PCB Exchange workflow. This incorporates the ease of PCB data processing for thermal modeling purposes using EDA Bridge accessed through its integration into PCB Exchange. Components and libraries: XTXML export of features (for 2R and Network Assembly) XTXML export for component editing was introduced in the last 2506 release which allows users to import models from Simcenter FLOEFD Package Creator utility, make adjustments to the models and then save the models in XTXML format to libraries. Manually created detailed models can also be exported in XTXML format. The Simcenter FLOEFD 2512 enhancement now has the option to export models of 2R and Network Assembly components. This enables you to build up a component library quickly. A note for CATIA V5 users. You can now edit XTXML files exported from Package Creator or create new XTXML library items with Simcenter FLOEFD for CATIA V5, as was introduced in version 2506 for other variants. Avoid the risk of losing EDA files To reduce the risk of losing EDA files from EDA Bridge for your many projects, often stored in separate folders, an option has been introduced to store EDA files nested to the main assembly. So users can choose from 3 options in settings now: 1) Model folder – files are stored next to main assembly (default option) 2) Sub-folder – files are in a separate folder next to main assembly 3) Specify – choose permanent path to the folder Want to apply these new features of Simcenter FLOEFD to your own models and gain momentum in your next simulations? CAEXPERTS can show you, in practice, how to use the new automatic cooling features, thermal resource optimizations, and model hydration to reduce setup effort, solution time, and memory usage.

With Simcenter Client for Git in the 2511 release, users can now delete branches directly from server collections. This capability makes it easier to remove unnecessary or obsolete branches at the source, helping teams keep their repositories lean and better organized. By decluttering the repository, server collections become smaller and more efficient, improving performance during repository operations. It also supports better project hygiene by maintaining a cleaner and more understandable version history. Overall, this enhancement enables engineering teams to manage their branches more effectively and maintain a streamlined, professional version-control workflow. Turbomachinery simulation improvements Meeting today’s efficiency and performance targets in turbomachinery requires highly detailed and integrated modeling capabilities. As systems grow more complex, traditional approaches often struggle to capture the full dynamics of rotating components, secondary air flows, and co-simulation behaviors across tools. Simcenter Flomaster 2511 introduces several targeted enhancements to address these challenges. Internal duct and forced vortex components have been upgraded to support turbine speed data directly, enabling more realistic and precise modeling of rotating secondary air systems. A new flow-tracking capability now enables engineers to visually trace which inlet sources contribute to the flow at any given outlet, providing deeper insight into system behavior and helping to accelerate diagnostics. Additionally, FMU export has been reinforced with support for implicit iterations and improved error handling, resulting in more robust co-simulation with Simcenter 3D Thermal . Together, these improvements deliver more accurate turbine speed modeling, clearer flow-origin identification, and smoother integration into whole-engine digital workflows, supporting faster decisions and more reliable development of high-efficiency turbomachinery systems.

Gas turbines can be found everywhere in our modern daily lives, as heart for sustainable and reliable power generation, as drives in various industrial, chemical or maritime applications or designed as aircraft engines in nearly every commercial or military aircraft. Although the technological idea of a gas turbine is not new and its first applications went back to early 1900, it is still an amazing technology which we can see every day and everywhere and it affects all our lives, even if we don’t know. And today, more than 120 years later, designing a gas turbine has not become a less complex engineering challenge, independently if designed for just a few kilowatts, for hundreds of megawatts as stationery or flying applications. Designing a gas turbine is an artful interplay of physics and covering multidisciplinary engineering challenges. Since 120 years, gas turbines have marked the spearhead of engineering innovation Gas turbine development and innovation are driven by ultimate targets to become cleaner, bigger, more silent and flexible. Reducing emissions and enhancing thermal cycle efficiencies have and will remain to be main drivers of new generations of gas turbines. Since decades aero engine and gas turbine manufactures are pushing the Bryton cycle towards higher efficiencies with improvements in materials, coatings, cooling technologies, combustion and more. Faster and closer cross-domain collaboration will be the next crucial factor enabling comprehensive cross-domain and cross-disciplinary design studies to uncover and unleash hidden potential. The only limit? Carnot! Simcenter X Advanced enables integrated multi-domain simulation engineering to design a micro gas turbine Power outages, while often brief, can severely impact critical infrastructure like hospitals and data centers. To ensure uninterrupted operation, robust emergency power units (EPUs) are essential and can ultimately even decide about life and death. To fulfill their purpose, these systems, often relying on fast-starting gas turbines, need to kick in within seconds. Hybrid EPUs, combining microturbines with battery storage, offers a powerful solution, with batteries bridging the startup time and providing immediate backup. When an emergency power unit needs to take over, there is usually no acceptance for failure. Imagine, in case of a hospital or intensive care unit power backup, it even becomes live critical. An emergency power unit (EPU) is a complex multidisciplinary engineering system. A system in which various elements need to interact to provide a reliable and functional system which can operate on point, as expected, when expected and in its best-balanced performance. Break down engineering silos and boost engineering productivity Emergency power units (EPU) have one ultimate goal, they must work reliable and provide power as expected in the case of cases without any option for failure. To design an EPU systems engineering is key to size the entire EPU modules and simulate the case scenarios. System modeling allows tailored engineering towards the application cases and provides the necessary physics-based parameters that are essentially needed for sizing the integrated modules or subsystems such as the gas turbine package. Within Simcenter X Advanced engineers have direct access to powerful Simcenter system solutions such as Simcenter Amesim , which allow a comprehensive system design. In This example, the EPU has an integrated 100kW micro gas turbine. By applying the gas turbine performance application within Simcenter Amesim , engineers can directly specify the architecture of the micro gas turbine and extract relevant pre sizing design parameters for the main gas turbine components. Multi-domain engineering solves multidisciplinary challenges best Designing the micro gas turbine requires a comprehensive interplay between different technical disciplines and various multi-domain simulation techniques. As an example, flow path components which have been perfectly designed towards aerodynamic performance need be checked against their to be manufacturability but also need to be checked if they are able to withstand the transient loading during operation. Thus, structural integrity investigation need to go hand in hand with aerodynamic design considerations to be most effective and to avoid unneeded iterations. But even if the single components fulfill all requirements towards aerodynamic and structural performance, the assembly may operate in safety risk condition, e.g. due to rotational resonance. Simcenter provides a comprehensive multi-domain simulation portfolio that ideally supports turbomachinery engineers to consider all those dependencies and multi domain challenges within one CAE environment. Simcenter X Advanced provides you multi-domain simulation access to Mechanical, Computational Fluid Dynamics (CFD), Systems simulation and Multidisciplinary Design Analysis and Optimization (MDAO) under a single license Design and validation of gas turbines, from early system level via component to entire whole engine modeling. With Simcenter X Advanced , engineers get now ultimate access to a comprehensive multiphysics CAE platform via one license. With integrated PLM connectivity and data management the digital thread is not a vision anymore, with Simcenter X Advanced it becomes real. When failure is not an option: Multi-disciplinary engineering excellence with Simcenter X Advanced In the demonstrative study “When failure is not an option: Designing a micro gas turbine in context of emergency power generation”, Simcenter X Advanced for multi-domain simulation put to the test.

  • CFD Simulation of Cement Pre-calciners with STAR-CCM+

    Cement production is one of the most energy-intensive and emission-intensive industrial activities, accounting for approximately 5% to 8% of global CO₂ emissions. In the modern dry manufacturing process, the pre-calciner plays a central and critical role, being the equipment where most of the limestone calcination occurs (decomposition of CaCO₃ into CaO and CO₂) and where between 55% and 65% of the system's total fuel is consumed. The efficiency of this equipment depends on a delicate thermodynamic balance between two main reactions: fuel combustion (exothermic process) and raw material decomposition (endothermic process). Due to the complexity of multiphase flow, where solid and gaseous phases interact at high speeds and temperatures, physical experimentation on an industrial scale is extremely costly and often impractical for detailed internal measurements. In this context, Computational Fluid Dynamics (CFD), with STAR-CCM+ , emerges as an essential tool for the optimization and design of these reactors. Through numerical modeling, it is possible to predict the hydrodynamics of the flow, heat transfer, chemical kinetics, and emissions, critical factors that act in the pre-calciner. Challenges and Solutions in Pre-calciner Simulation CFD simulation of pre-calciners presents challenges associated with the multiphase, thermal, and reactive complexity of the process. The cohesion and agglomeration of fine raw meal particles significantly alter the flow and calcination efficiency, requiring advanced particulate phase models. On a larger scale, the formation of gas-solid clusters introduces heterogeneities that render homogeneous drag models inadequate. Heat transfer constitutes another critical point, due to the very thin thermal boundary layers along the walls, whose correct mesh refinement is unfeasible in complete industrial geometries. As a solution, coupling CFD with simplified mechanistic models allows for realistic thermal estimates with reduced computational cost. Furthermore, the strong coupling between exothermic and endothermic reactions imposes high nonlinearity on the system. In the context of emissions reduction, oxy-fuel combustion presents additional challenges, such as ignition delay and high CO₂ concentrations, which can be mitigated by multi-stage combustion and pre-gasification strategies, ensuring operational stability and low NOx levels. CFD Simulation of the Pre-calciner This numerical simulation study, developed in STAR-CCM+ , focuses on the detailed analysis of combustion in a large-scale cement pre-calciner, emphasizing the evaluation of the characteristics of the oxy-fuel process and its impacts on the thermal efficiency and operational stability of the equipment. The modeling was conducted using a non-premixed combustion model, incorporating the chemical kinetics of coal, devolatilization phenomena, NOx formation, and thermal radiation effects. The kinetic mechanism employed is presented in Table 1. It should be noted that, in this study, the particulate model of calcium carbonate (CaCO₃) was not considered, focusing the analysis exclusively on the combustion of the solid fuel. Reaction Equation R1 2CO+O2->2CO2 R2 C + 1.5 O2 -> 0.5 CO +0.5 CO2 R3 C + CO2 -> 2CO R4 CaCO3 -> CaO + CO2 R5 Devolatilization Table 1. Chemical Reactions The numerical model adopted the following simulation assumptions: steady-state regime, ideal gases, Eddy Break-Up (EBU) combustion model, k-ε Realizable turbulence model, thermal NOx model, and coal particles modeled in a Lagrangian fashion, with an average diameter of 50 μm. The computational mesh was strategically refined in regions of higher thermal and chemical gradients, such as the primary and tertiary air intake zones and coal injection zones. Boundary conditions were defined to reproduce real operational scenarios, including prescribed air and fuel flow rates, ensuring greater physical representativeness of the model. Figure 1. Geometry and computational mesh Figure 2 shows the temperature field inside the pre-calciner. It can be observed that the regions near the central axis of the flow reach temperatures above 2100 K, evidencing intense combustion activity. In contrast, a low-temperature zone is identified near the inlet nozzles, associated with the high concentration of air in these regions, which promotes dilution of the fuel mixture and locally reduces thermal efficiency. The analysis of the thermal field allows us to assess whether the regions of interest operate within the appropriate temperature range for the process. Figure 2. Temperature profile Complementing this analysis, Figure 3 presents the axial temperature profile along the pre-calciner. A thermal peak is observed in the first 10 meters, resulting from the initial combustion reactions of the coal, followed by a gradual reduction in temperature along the flow, as the fuel is consumed and the gases are diluted. Figure 3. Temperature plot Figure 4 illustrates the concentration profiles of CO, CO₂, and O₂ along the height of the pre-calciner. The CO₂ concentration progressively decreases as the gases rise, reflecting chemical interactions and flow dilution. CO shows peaks near the burner region, associated with centralized coal injection and incomplete combustion. Due to the low local availability of oxygen, some of the CO is not oxidized to CO₂, resulting in a lower CO₂ concentration at the equipment outlet. Figure 4. Concentration profiles: (a) CO; (b) CO2; (c) O2 Figure 5 shows the evolution of the molar fraction of the main components along the vertical axis of the pre-calciner. A significant consumption of O₂ and CO₂ is observed, concomitant with the generation of species such as volatiles, CO and H₂O, characterizing the dominant stages of the coal combustion process. Figure 5. Molar fraction plot Finally, Figure 6 presents the velocity field and streamlines, highlighting the direct influence of the pre-calciner geometry on the flow. Recirculation zones near the tertiary air inlet are prominent, as are regions of low turbulence ("dead zones"), which represent potential areas for the accumulation of unreacted material. Although these regions are associated with flow separation, they also play a relevant role in the conduction and mixing of gases. These results indicate the need for geometric adjustments to optimize the flow, reduce energy losses, and improve the overall efficiency of the equipment. Figure 6. Velocity Profile Conclusion The results presented demonstrate that the use of STAR-CCM+ as a Computational Fluid Dynamics (CFD) platform for the integrated analysis of fluid dynamic, thermal, and reactive phenomena governing the performance of cement pre-calciners is effective. The robustness of the software allowed for consistent modeling of non-premix combustion, species transport, thermal radiation, and particulate behavior, enabling a faithful representation of industrial operating conditions. The adopted approach proved particularly relevant in the context of Oxy-Fuel combustion, where the coupling between chemical reactions, heat transfer, and particulate dynamics imposes additional challenges. The use of appropriate models makes it possible to evaluate operating and design strategies, such as the optimization of air and fuel injection, geometric adjustments, and burner configurations, aiming at reducing emissions, increasing energy efficiency, and greater operational robustness. In this way, CFD simulation is consolidating itself as a strategic tool for decision-making, retrofitting, and developing new technologies in cement plants, reducing dependence on empirical testing and accelerating the transition to more efficient and environmentally sustainable processes.   References ZHENG, Qiang et al.

  • CFD simulation at your Christmas dinner

    Christmas is a time marked by gatherings, celebrations, and, of course, the preparation of traditional dishes. Among them, roast turkey occupies a prominent place. But what happens inside the oven while the roast is being prepared? To answer this question in a technical and accessible way, a simulation was performed using Simcenter FLOEFD , a Computational Fluid Dynamics (CFD) software, with the aim of analyzing air circulation and heat distribution in a convection oven during the preparation of a turkey. Model of a turkey in a convection oven in Simcenter FLOEFD The simulation scenario The turkey did not have exactly the correct dimensions, being just a solid block. There was no cavity for stuffing or for the neck, therefore the measurements were estimated visually and some cuts were made. As one of the most relevant issues was the amount of airflow through different spaces (in the cavities and under the turkey), some objects were created to collect this data. The oven was configured in convection mode, with a fan located at the rear, responsible for propelling air horizontally over the roasting area. For this model, the height of the rack is set at just over 1mm above the bottom of the roasting pan. Turkey cavity This model was run as a snapshot, meaning the turkey temperature was set at a point where it was not yet fully cooked (120°F). The oven temperature was set to 375°F, with the heating elements positioned at the bottom of the oven operating at a slightly higher temperature of 400°F. Boundary Conditions for Turkey Roaster Analysis Initially, the flow lines are observed, which are analogous to the smoke lines shown in wind tunnel tests used in car commercials. These lines indicate the direction of airflow. The fan was defined as the starting point of the flow lines. Although the flow lines exhibit quite chaotic behavior, it is possible to extract relevant information from them. By sectioning the model, the interior of the roaster and the turkey cavity become visible. Compared to the flow lines outside the turkey, it is observed that little air enters the roaster and passes under the turkey, and an even smaller amount passes through the interior of the turkey. This result was expected, especially regarding the airflow in the cavity. The fan propels the air transversely to the width of the turkey, not along its length. For the air to enter the cavity, it would be necessary to go around the turkey and then make a 180-degree turn, which is not physically plausible. Furthermore, due to the large size of the turkeys, it is not possible to orient them in the same direction as the airflow generated by the fan. The airflow from the oven fan surrounds the turkey, whose color varies according to the temperature The oven fan's airflow is directed towards the roasting pan and the turkey cavity Observing a contour plot of air velocity passing through the central plane of the turkey and the oven, it can be seen that the air velocity through and under the turkey is very low, while higher values ​​are observed above the turkey and below the roasting pan. Low-velocity air is considered to be air whose magnitude is comparable to that of a natural convection oven, where the typical air velocity is on the order of 0.2 m/s. Therefore, there is no significant gain in heat transfer provided by the fan, since most of the turkey's surface is subjected to air velocities below 0.2 m/s. Air Velocity Contour Graph For a more precise understanding of this behavior, a graph of the air velocity near the surface of the turkey is observed. The image has been divided into two parts: one representing the surface of the turkey facing the fan and the other showing the opposite side. The difference between the two regions is evident. As a consequence, one side of the turkey tends to cook or dry out more quickly than the other if the food is not rotated periodically. Higher air velocities result in more intense convection, a principle illustrated by the act of blowing on soup to accelerate its cooling. Speed ​​close to the surface of the turkey, near the fan Air velocity near the surface of the turkey, opposite to that of the fan. Returning to the contour plot, when analyzing the temperature distribution, it is clearly observed that the air inside the turkey has significantly lower temperatures. This occurs due to air stagnation, since there is no effective circulation of hot air inside the turkey. It is also observed that, below the turkey, in the space of approximately 1 cm (0.4 inches) provided by the grill, the air temperature is lower than that of the rest of the oven. Again, this behavior is explained by the limited circulation of renewed hot air in this region. Air temperature contour graph along the centerline of the turkey The question arises as to why air has difficulty penetrating the space between the turkey and the bottom of the roasting pan. Observation of the flow lines indicates that the cause is essentially the same as that which prevents air from entering the inside of the turkey. The air from the fan tends to follow the path of least resistance. To flow under the turkey, the air would need to go around the wall of the roasting pan, descend through the space between the turkey and that wall, and then make a 90-degree turn to flow under the turkey. Along this path, there is a reduction in speed and a loss of temperature. Both factors are relevant, since colder air tends to descend. Furthermore, since the flow velocity is lower than that of a natural convection current, the warm, renewed air cannot displace the air already present in that region. For this reason, it is observed that the air reaches the roasting pan, but cannot advance under the turkey, instead recirculating near the wall of the roasting pan. Contour graph of air velocity and streamlines along the width of the turkey The images provide a good qualitative understanding of the phenomenon; however, in many cases, a quantitative analysis is necessary. Data evaluation indicates that the oven fan moves approximately 22.8 CFM of air. The airflow that effectively enters and exits the roaster is about 0.35 CFM, which corresponds to approximately 1.5% of the total fan flow. Regarding the air entering the turkey cavities, the inflow and outflow were analyzed in both the neck cavity and the larger rear cavity. The measured flow rates were 0.08 CFM and 0.146 CFM, respectively. From these results, it is concluded that the stuffing is not responsible for preventing air circulation inside the turkey, since this circulation is already intrinsically very limited. This does not exclude the effect of the additional thermal mass of the stuffing, which can result in longer cooking times and drier meat—a topic that deserves specific analysis. Nor should one expect significant air circulation under the turkey capable of producing a completely crispy skin. A higher rack or a roasting pan with lower sides might offer some improvement, although this effect is questionable. In practice, using a rack or vegetables like carrots, celery, or potatoes serves a similar function, elevating the turkey and keeping it away from the accumulated fat.

  • From stardust to simulation: The power of SPH particle refinement

    Believe it or not, the Smoothed-Particle Hydrodynamics (SPH) technology, which has significant applications today, was actually developed for astrophysical purposes. It was originally used to simulate the dynamics of galaxies and the behavior of stars and planets: Smoothed Particle Hydrodynamics | Annual Reviews Monaghan, J. J. 1992. “Smoothed Particle Hydrodynamics.”, Annual Review of Astronomy and Astrophysics 30:543-74. doi: 10.1146/annurev.aa.30.090192.002551. Just like cosmic formation, where countless particles coalesce into refined structures to form stars and planets, the SPH solver in Simcenter STAR-CCM+ 2510 now offers local particle refinement. But you don’t have to go to outer space to make use of this capability: it can actually be used for any down-to-earth application, like, for example, to better capture the oil around planetary gears. And no, planetary gears are not an astrophysical application, even though this thing is pretty close to one: Enhance simulation precision with SPH particle refinement technique In previous versions of SPH in Simcenter STAR-CCM+ , achieving higher fidelity required refining the particle size, which inevitably increased simulation time. Conversely, opting for faster simulations meant coarsening particle size, sacrificing accuracy. This is the classic CFD dilemma with no easy solution. Now, with version 2510, Simcenter STAR-CCM+ introduces local particle refinement for the SPH solver, allowing you to enhance flow accuracy precisely where it’s needed without necessitating a fine particle size across the entire fluid domain. This new capability enhances precision in critical areas while maintaining efficient simulation time, offering a balance between local high-fidelity results and computational performance. The performance improvement largely depends on the application and the size of the refinement area. In the SPH solver’s adaptive time-stepping, the chosen time step is still determined by the finest particle size. Consequently, the performance boost is not driven by the time step but achieved by reducing the total number of particles compared to a fully refined particle simulation. As a result, the more localized and specific the refinement areas are, the greater the performance gains you will experience. As illustrated in the animation, you now have the ability to locally create geometry particle refinement criteria using block, cylinder or/ and sphere shapes. In the example, cylinder refinement criteria have been defined around each gear to accurately capture the oil distribution close to the teeth. Your simulation can incorporate one or multiple refinement shapes, and they can even overlap as needed, especially when dealing with complex geometries such as gear teeth. You can define up to 10 levels of refinement, allowing particle size specifications to go below one micrometer, starting from a base particle size of 1 mm. Also noteworthy is the ability to assign a coordinate system to the refinement shapes. This is particularly useful if you need the refinement to follow a moving solid, ensuring it maintains an accurate resolution while moving along a trajectory in space. To demonstrate the higher fidelity benefit for this planetary gear application, this chart depicts the average wetted surface over time. As shown, the simulation using particle refinement (particle base size of 1 mm using two levels of refinement) achieves accuracy that closely matches the finest simulation (0.25 mm). In contrast, it outperforms the coarse simulation (1 mm), highlighting the effectiveness of particle refinement in balancing precision and computational efficiency. Another key advantage of particle refinement is its significant reduction in memory consumption. As illustrated above, using particle refinement results in a fourfold decrease in memory usage compared to the finest simulation, enabling you to efficiently handle more complex cases. Simplify planetary gearbox simulation with just a few clicks Just as effortlessly as planets revolve around the sun in our solar system, setting up a planetary gearbox in Simcenter STAR-CCM+ has never been easier. Starting with version 2506, the new kinematics solver allows for the use of Planetary Gear and Revolute Joint Body Couplings, enabling you to configure motions with just a few clicks. Additionally, version 2506 introduced enhanced data analysis capabilities. You can now measure mass flow or various other quantities across section planes, thanks to the compatibility of the SPH solver with constrained plane and arbitrary section-derived parts. Furthermore, visualization of the free surface is now possible using the SPH solver’s compatibility with the iso-surface derived part of the liquid volume fraction. Those enhancements in the motion and data analysis contribute to a faster setup and getting more insights into the quantitative solution. Accelerate SPH simulations with lightning-fast GPU workflows In Simcenter STAR-CCM+ 2510 , SPH simulation feels akin to traveling at the speed of light, thanks to seamless GPU acceleration compatibility throughout the entire workflow. The solver supports native GPU acceleration since version 2410 for single GPU and expanded to multiple GPUs in version 2502. With the latest version 2510, data analysis capabilities are now also ported to GPU hardware. As a result, you can now utilize and visualize point probes, free surfaces, constrained plane sections, and arbitrary sections derived parts up to five times faster compared to before. This allows for rapid solution analysis, maintaining your workflow at a lightning-fast pace. In this specific example, running the planetary gear lubrication simulation on an NVIDIA RTX6000 GPU achieves a speedup of nearly five times faster compared to using 56 CPU cores. This demonstrates that the entire workflow for this application, including particle refinement, is fully optimized and compatible with GPU acceleration. Explore new simulation frontiers with enhanced SPH capabilities Simcenter STAR-CCM+ continues to advance its SPH solver with significant enhancements, including local particle refinement, a streamlined workflow for planetary gears, and additional data analysis capabilities, as well as robust GPU acceleration. With more accuracy, faster setup, and runtime, the SPH solver may help you reconnect with your inner child by looking at all new types of planets and stars in planetary and sun gears. And ultimately, we want to enable you “to boldly go where no (wo)man has gone before.” Perhaps even for your SPH simulation, one day space will become the final frontier.
