Abstract
A study of a Formula 1 wing in ground effect using CFD tools in order to establish guidelines for an accurate numerical approach on this type of flow simulation comparing various types of turbulence models and mesh models provided by commercial CFD package Star-CCM+. The work focuses specifically on RANS simulations of the Formula 1 Tyrrel 026 front wing for which experimental work has been conducted at the University of Southampton’s moving belt wind tunnel. Spalart-Allmaras and k-ε turbulence models are evaluated as well as dodecahedral, hexahedral and tetrahedral element mesh models. The coefficients of lift and drag are plotted against the height/cord ratio and compared with the experimental results. The pressure coefficient distribution, wake velocity profile and boundary layer profile are also compared. The flow structures were evaluated with respect to the ones observed by PIV techniques in the experiment. The lift coefficient was well predicted but drag showed divergence for higher ground clearances. The simulation was able to reproduce the experiment’s flow structures such as the Venturi effect, tip vortex and the increase of separated flow with the wing closer to the ground. The simulation was also able to reproduce the downforce reduction phenomenon.
