Toward highly accurate flow analysis for study of Reynolds number effect on cascade characteristics, a numerical method was developed, which method was capable of flow simulation for widely ranged operating conditions. The developed code utilized the CCUP method in which both incompressible and compressible flows could be simulated in a same way with high-order accuracy. Baldwin-Lomax turbulence model was incorporated so far, and turbulence transition point was determined based on the suggestion by Baldwin and Lomax. Flow simulations were performed on single blade configuration as well as a compressor cascade composed of C4 blades. It was verified that the developed method had capability for wide ranges of Mach number and Reynolds number, though further progress should be done for more accurate simulation for the cases with shock wave and boundary layer separation.
