Useful Correlations for Cavitating Water Jet

Abstract

In order to use a submerged water jet accompanied with cavitation for practical applications, a cavitating jet was investigated experimentally. The static pressure on the impinging surface was measured to make clear the structure of the cavitating jet. The erosion tests were also carried out to measure the cavitation intensity. The optimum standoff distance at different cavitation condition was correlated by the cavitation number at the nozzle and the local cavitation number on the target. The relation between the cavitation intensity and the hydraulic parameters was also revealed. © 1998, The Japan Society of High Pressure Science and Technology. All rights reserved.
