文摘The CSCM-S algorithm proposed by Lombard et al.is a very attractive tool for solving multidimensional Euler and Navier-Stokes equations.However,it is not economical due to the use of global sweeps in the whole computational domain.In this paper we suggest a modified strategy,which combines a single-marching technique for supersonic dominated region with a multi-sweep procedure for pure subsonic and complex flowfield.The new algorithm may save significantly CPU time and is more suitable for engineering applications.
