hitleo Guest Posts: n/a	hello eveyone i am now programing Meng Sing Liou's AUSM(advection upstream splitting method) to a code for numerical simulation of axial compressor,but i have a big problem. if there is no viscous term, the code can convergence. if there is viscous term, the code can't convergence. the mass flow will always minish and the code will divergence. i use B-L turbulence model, it is no problem with central difference scheme for axial compressor. how can i solve this problem? i have locked one month. please help me!!! thank you very much!!!!
