In this paper, the vortex method presented in the previous report is used to analyze the separated unsteady flow in a centrifugal impeller for various discharge coefficients Ce=Q/Qn (Ce=0.6, 1.0, 1.5). From the results of the numerical analysis, the unsteady phenomena of the flow between the blades are clearly shown and are seen to be changed with both the formation of a reversed flow area and the emission of separated vortices from the outlet of the impeller as time elapses. Moreover, the characteristics and the slip factor of the centrifugal impeller are also discussed qualitatively.
