In this paper, the numerical simulation software ANSYS-CFX is used to simulate the flow field in the radial pump together with the SST k-ω turbulence model. The cross-power spectra analysis method is used to examine the internal rotating stall in the diffuser region. The rotating stall characteristics occurring in the part-load condition inside the vaned diffuser were discussed by using the cross-power spectra method
