Abstract
In view of the complexities of under-vehicle flow, a few suitable models and a corresponding program were developed and used to simulate the3D external flow field around a Changan Star minibus in this paper. The computation result of drag coefficient reasonably coincides with that of road test. Based on the results of numerical simulation, the complex turbulent flow under the vehicle were analyzed, laying a foundation for controlling under-vehicle flow, and further improving vehicle aerodynamic characteristics.
