Abstract
Ten sets of mesh parameters are considered in building the model for aerodynamic numerical simulation of a CHERY sedan. It is found that, in comparison with the wind tunnel test data, the error in drag coefficient computed by using these meshes is less than 4%. Especially, in one case, the error is found within 1%. The CAE method discussed in this paper can be used to assist the design of vehicle aerodynamics.
