Numerical simulation of 3D viscous flows through multistage transonic fans and compressors was carried out with circumferential mixing model between adjacent blade rows. Computations provide rapid convergence by the use of LU-SGS implicit method. Resolutions of shocks in transonic flow field are improved with a high- resolution scheme. Numerical calculations were performed on a two-stage transonic fan and a five-stage compressor. The two-stage fan flow predictions show a good agreement with experimental data....
