Experimental and numerical study on cavitation pulsating pressure of water-jet propulsion axial-flow pump.

PLoS ONE
Cavitation may occur in water-jet pump during operation of water-jet propulsion vessel, and once cavitation occurs, the tip clearance pulsating pressure of the impeller may be intensified, resulting in increased vibration of the water-jet propulsion unit.
