Abstract
Recently, submerged water-jets are very often applied for cutting, peening and cleaning. In such a jet-working-capacity, the shedding of cavitation clouds and the vortex cavitation around the jets are the most important factor. In order to clarify the mechanism of the shedding around the jets, we systematically observe the aspects of the jets, by means of a highspeed-video-camera, whose maximum framing rate is 40500 per second, by using a laser-light-sheets. And the digital images taken by the video camera are stacked to a stereoscopic display to examine the jets behavior changing with time. The cavitation clouds and the vortex cavitation are stereoscopically displayed by the digital image-processing-technique.
