Abstract: 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”. When the cavitating jet is injected into a
surface, cavitation is collapsed, producing impacts. Although
cavitation impacts are harmful to hydraulic machinery,
impacts produced by cavitating jets are utilized for cleaning,
drilling and cavitation peening, which is a mechanical
surface treatment to improve the fatigue strength of metallic
materials in the same way as shot peening.
