Numerical Simulation of the External Flow Field Around a Bluff Car*

Computational Fluid Dynamics, CFD, emerges as an advanced investigative means in the fields of automobile, aeronautics and aerospace. It reduces the wind tunnel experiments. In this paper, it is stated that CFD is applied to the automotive aerodynamics with Finite Element Method, FEM. MSC.Patran is used as a preprocessor and MSC.CFD as a solver. By that we get the pressure field and velocity field around the vehicle, then acquire air drag coefficient (Cd) and compare it with the wind tunnel experimental results. The conclusion of the comparison is satisfying
