In recent years, low fuel consumption attracts much attention in the automotive industry from the viewpoint of environmental problems. The aerodynamic drag reduction of a car is one of the most important issues for low fuel consumption. However, the flow mechanism in a wheel house has not been clarified in detail. On the other hand, recently it is shown open?source CFD toolbox OpenFOAM is usefulness. Therefore in the present study the flows around a car are simulated by RANS using OpenFOAM, in order to investigate the flow in wheel houses. Two cases are computed; tire with wheel and tire without wheel.
