Abstract

Collapse of cavitation in flow passage of impeller for centrifugal pump was stimulated by CFX to numerically stimulate internal features of cavitation when pressure at entrance continuing to decline. Results of numerical simulation and tests presented consistent tendency. Cvol in the flow passage of impeller was zero for a while in the occurrence of cavitation collapse and then increased sharply. After reaching a certain value, Cvol began to increase slowly. The amplitudes of head fluctuations increased with decreasing flow within the interval prior to a specific value and then increased with increasing flow.
