Cavitating Jet: A Review

Applied Sciences, 2020
When a high-speed water jet is injected into water through a nozzle, cavitation is generated in the nozzle and/or shear layer around the jet. A jet with cavitation is called a “cavitating jet”.

Experimental Study on the Unsteady Characteristics and the Impact Performance of a High‐Pressure Submerged Cavitation Jet

Shock and Vibration, Volume 2020, Issue 1, 2020., 2020
High‐pressure submerged cavitation jet is widely used in the fields of material peening, petroleum drilling, and ocean engineering. The impact performance of the jet with intensive cavitation is related to the factors such as working condition and the nozzle geometry. To reveal the relationship between the nozzle divergent angle and the jet pressure on
