Cavitation and Erosion in Submerged Water Jet.

open access: yesTHE REVIEW OF HIGH PRESSURE SCIENCE AND TECHNOLOGY, 1998
This paper is concerned with cavitation and erosion in submerged water jet. Impulse force generated by cavitation bubbles in the jet is measured by an impulse force gauge. The accumulated count of impulse force per unit time is shown against the impulse force and the standoff distance from the nozzle exit.
