A research on numerical simulation of external flow field of a self-owned brand vehicle was conducted by the use of fluid mechanics analysis software STAR-CCM+, and reasonable results were got by the comparison of trial data and simulated data, the pressure distribution chart and acoustic power chart were calculated as well. Some suggestions were put forward in order to reduce the drag coefficient, improve the performance of the car and comfort of the driver. Results can provide some references in shape design.
