This paper presents Partially-Averaged Navier-Stokes (PANS) simulation of the flow around generic vehicle at different yaw angles. The results of PANS show not only excellent agreement with the experimental data but also large savings in the computer effort compared to LES predictions. Simulations on several computational grids show that PANS adapts to the existing grid making the prediction accurate on affordable computational grids.
