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.

Partial Cavity Instabilities and Re-Entrant Jet

, 2001
The purpose of this talk is to give an overview of different instabilities which can affect partial cavitation. We shall focus on the case of a unique partial cavity attached to an isolated hydrofoil or to the throat of a Venturi. Another paper presented
