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. |
