In order to overcome the Reynolds number limitation of Cartesian gird method,the optimization technology is carried out and the wall function model is applied in Cartesian mesh. It provides a method to improve the accuracy of boundary layer simulation for Cartesian mesh, and reduce the dependence of numerical results on grid scale in the meantime.
