摘要

In this paper the high order compact scheme on non-uniform grids is extended from 2D to 3D, and the additive-correction multigrid technique is adopted to accelerate convergence rate. Numerical performance of the adopted method is validated for different boundary conditions. The results show that: this method can be effectively used to solve pressure Poisson equation of the NS equation.
