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.

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.
