New Generation CFD Code for Formula 1 Car Development

Résumé des résultats (Abstract) (Allemand)

Sauber Motorsport AG develops, produces and runs Formula 1 racing cars, for which aerodynamic performance is a key factor to success. At Sauber, large part of the aero-development is performed with CFD. Improving the CFD solver in terms of (1) speed and (2) reliability in capturing the flow physics are the main goals of the project, thus leading to shorter product development times. CFD at Sauber is based on the open source toolbox OpenFOAM, so that both goals can be achieved with corresponding implementations. In the project, (1) state-of-the-art acceleration techniques will be implemented, in order to achieve a speed-up factor of 3 to 10 of the solver (compared to the available technology) for meshes up to 1,000,000,000 nodes. Furthermore additional (2) flow physics capturing modules will be implemented, in order to improve the reliability of the CFD predictions. Turbulence modeling, conjugate heat transfer and fluid-structure interaction are here the main topics, together with unsteady methods.
