Research on Characteristics of External Flow in Region of Passenger Car's Wheels

摘要

The technology of computer modeling and simulation is applied to compute and analyze external flow field of the wheels for a medium-class passenger car. Comparisons are drawn between the different results of flow field around the wheels in case that the flow field is modeled and solved with the two different boundary conditions of wheel: one is the stationary wall and the other is the rotating wall. And further we investigate the characteristics of external flow field of rotating wheels. It is concluded that the boundary condition of rotating wheels should be introduced when simulating and testing.
