Abstract

It is known that water-jet with cavitation clouds shows unsteady behavior and causes high impact. It is useful for not only the water jet technology but also various engineering fields. The unsteadiness of cavitation clouds is one of the most interesting problems for the use of the cavitating water-jet. In this study, we tried to estimate the behavior of the cavitation clouds at the impingement. Especially, the behavior of the cavitation clouds was observed using a high-speed video camera triggered by the cavitation impact, and analyzed with an image processing technique.
