Limiting Flow Cavitation Number of Water Jet Pumps

Bulletin of JSME, 1982
The method to determine the cavitation number for cavitation-limited flow condition in a water jet pump was theoretically and experimentally studied. Through visualization of the cavity bubbles, it was observed that a shock wave was developed in the diffuser once the cavitation-limited condition was reached.
