Abstract: The AUSM+ scheme which was developed on structured grid has been extended to be used on unstructured grid. The monotone linear reconstruction procedure using Green-Gauss theory is utilized to obtain second order spatial accuracy. Barth's limiter is employed to prevent solution spurious oscillations. An adaptive multigrid strategy is used to accelerate the convergence. Numerical results for several test cases are presented.

Key words: unstructured grid, finite volume method, adaptive grid, multigrid method
