An implicit finite volume upwind space-marching CFD solver,i. e. Single-Sweep Parabolized Navier-Stokes Algorithm(SSPNS),is developed by integrating the PNS equations with LU-SGS method in the streamwise direction.

• 在有限体积法框架下,采用空间推进算法SSPNS(Single-Sweep Parabolized Navier-Stokes Algorithm)求解抛物化NS方程(即PNS方程),在流向采用LU-SGS隐式积分,而横向无粘和粘性通量则分别采用AUSM系列格式和中心格式计算。
