Study on the Characteristic of Self-Excited Cavitation Oscillation in Pump-Piping System

Abstract:

In order to analyze the characteristic of the self-excited cavitation oscillation occurred in an inducer-centrifugal pump-piping system, a novel cavitation dynamic model is present to simulate the dynamic characteristic to capture the limit cycles, the characteristics of inlet pressure and the flow rate. The results of numerical experiments indicate this cavitation dynamic model is very suitable to simulate the characteristics of the self-excited cavitation oscillation; the calculated limit cycle of flow rate vs. inlet pressure is consistent with experiment; the cavitation pocket decreases as the flow rate and inlet pressure rise.
