Two different CFD methods, a time marching method and a pressure correction(or based) method, are developed and applied to centrifugal compressor impellers to investigate their validity of applications. 8 impellers are selected for analysis, among which 7 impellers are open to the public, ranging from low to high level of pressure ratio. In all cases, the time marching method gives a satisfactory solution, but the pressure correction method does not. Up to about 18% less level of total-to-total pressure ratio is predicted by the pressure correction method as the level of the impeller pressure ratio increases up to about 10. The drop of total pressure ratio is caused by the underestimation of static pressure rise which seems to be attributed to inappropriate linearization and discretization of the pressure/density coupling terms in the pressure correction equation.
