Although the potential of cavitating water jets for augmenting the fragmentation (or other applications, such as cleaning) ability of continuous water jets has been known for a nutfiber of years, their use is not as widespread as anticipated. Good performance of cavitating water jets has mainly been documented under submerged conditions, where its usefulness is limited, for a given set of operating conditions, to very short standoff distances. In this paper, sample results of flow visualization, erosion of aluminum and cutting or fragmentation of rock samples are presented in an attempt to elucidate the influence of geometrical and operating parameters on the performance of cavitating water jets. Possible advantages of artificial submergence through special nozzle design or an external water shroud are also examined. The ultimate goal of this study is to establish the usefulness and limitations of cavitating water jets for fragmentation or fracture of hard brittle materials such as socks and concrete and other applications.
