Using a prototype of terrain car as example, a process of flow simulation around a vehicle with rotating wheels is described by using a professional CFD (Computational Fluid Dynamics) software. The influence of the wheels motion on main aerodynamic characteristic of the car, drag, is studied in two ways, commonly used in wind tunnels [10], respectively with the moving wall approach and with the aid of the rollers for the wheels rotation. The conclusions are demonstrated by the results using the relative drag increment and by the computergraphics visualizations. There are also presented some considerations concerning the importance of the rotating wheels in aerodynamics of the road vehicle and the opportunity to simulate it in a virtual environment. The present contribution is a companion paper by Huminic & Chiru (2004).
