Abstract

The unsteady flow structures at the rear end of a car and in its wake strongly influence its handling characteristics. State of the art research on this topic often employs strongly simplified car models, such as the Ahmed body. Due to their high degree of ab- straction, however, the insights gained cannot be fully transferred to the development of production cars. To close this gap a new reference car model for aerodynamic research - the DrivAer body - is proposed in this paper. Its geometry and validation data will be published to encourage independent studies. The investigations of both the Ahmed body and the DrivAer model are conducted both numerically and experimentally. The transient numerical simulations were carried out using Large Eddy Simulation (LES) and the Scale-Adaptive Simulation Shear-Stress Transport (SAS SST) turbulence model of the open source software OpenFOAM®. These results are compared to time-accurate surface pressure measurements and force measurements. Initial results show good agreement with existing experimental data.
