On the basis of a certain type of car,the external flow field model including rearview mirror,wheels and body modeling is established,and the outflow field of wheels under the condition of static and spinning is numerically simulated,compared and analyzed by Fluent software. The simulation results show that the rotating wheels affect the aerodynamic drag and the aerodynamic lift of the whole automobile,at the same time,the rotating wheels also have a great influence on the bottom of the body,stern and the eddy current form and scale at rearview mirror. Therefore,the rotating wheels have an important influence on the analysis of vehicle outflow field,which should not be neglected.
