Use STAR-CCM+ software for CFD simulation is proposed in order to overcome the limitations of wind tunnel tests in the automotive design process. This paper presents the details of aerodynamic simulation process of a SUV and its validation with the experimental results available from the wind tunnel tests. The results are compared for different configurations. This study also includes the effect of different wind speeds and yaw angles on the coefficient of drag. The results show that CFD numerical simulation method is feasible and effective, can reduce the time and cost of wind tunnel tests.
