A method moving vehicle noise simulation was given. Geometric model of a sedan car is built using Pro/E. Analytical model was built by meshing using GAMBIT. FLUENT was applied to solve the steady simulation using RANS method. The noise source distribution of the vehicle surface is predicted based on the Broadband Noise Source Model. The unsteady simulation is solved using LES method. The far-field noise is predicted based on the FW-H model. Then a comparative analysis of the simulation result and the test result is carried out. External aerodynamic noise simulation result calculated using CFD method is in good agreement with theories and test conclusions. It proved that fluctuating pressure has a close relationship with flow velocity and static pressure, and flow separation is the direct cause of the vehicle external aerodynamic noise.
