"The paper presents the numerical simulation of the cavitating flow phenomena in the suction part of a radial-flow multistage water pump with an inducer and a high rotational speed. Besides the cavitation inception and the drop of the pump total head the CFD analysis studies the possibility of the cavitation surge and quantifies the risk of cavitation erosion for different flow conditions. ANSYS CFX was used to solve the URANS equations coupled with the Rayleigh-Plesset Model and the SST-SAS turbulence model. The erosion risk is estimated from the energy dissipated during the collapses of individual bubbles. The cavitation instability in the backflow vortices has been detected at 60% of the optimal flow coefficient close to the NPSHr value." .
