To effectively process CFD works in early stage of aerodynamic developments of vehicles, simple but semi-complex configurations of the vehicle underbody should be pursued. Large eddy simulation (LES) was performed on the flow around the vehicle with a semi-complex underbody configuration designed at Volvo Car. Computations with CFD code “FrontFlow-red” were performed for both flat and semi-complex underbody configurations. Unstructured meshes of approximately 22 and 23 millions were used respectively. Differences in the flow fields with flat and semi-complex underbody configurations and rotational effects of the wheels are discussed. LES results are also compared with those with Reynolds averaged Navier-Stokes (RANS) computations.
