Study on the Evolution Patterns of Cavitation Clouds in Friction-Shear Cavitating Water Jets

Applied Sciences
Current cavitating water jet technology for mineral liberation predominantly relies on the micro-jet impact generated by bubble collapse. Consequently, conventional nozzle designs often overlook the shear effects on mineral particles within the internal ...

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.
