Abstract:In order to solve the problem of the poor quality for grid generation in the region of the wheel against the ground,algebraic method was combined with elliptic equation method,the block-structured grid was used,and then three schemes of grid topological structure were discussed to decide on the best one.After the selected scheme was applied to the grid generation of the flow-field around a certain made-in-China sedan and its wheels,highquality grid cells and reasonable numerical result were attained,which validate the method and the selected scheme adopted in this paper.
Keywords:automotive aerodynamics  external flow-field  numerical simulation  grid generation
