CFD Analysis and Experimental Verification of Multi-Stage Centrifugal Pump with Multi-Outlet Options

Abstract:

A three-dimensional flow in a whole multi-stage centrifugal pump with multi-outlet options is numerically simulated using CFX software. The flow field distributions inside pump with different outlet setting are observed and analyzed. Specially, it is found that the downstream of the pump outlet is considerably different from upstream of the pump outlet and forms some self-circulating vortexes inside the stage with more energy loss. The pump performance curves are predicted based on the flow simulation, showing that efficiency rises up while the pump outlet is set at the backward stages. Finally, CFD results are verified by comparing predicted performance curves with the experimental ones.
