This paper describes the generation of cavitation by pulsed water jetting and its capability for utilization. A submerged cavitating pulsed water jet was realized by a system that we developed. In this study, we visualized the cavitating water-jet in water-pool by laser-sheet imaging technique. And an experiment was carried out to evaluate the capability for surface processing of metal by impinging jet. From the experimental result, it was found that the present system have a capability for shot-peening of metal surface at longer stand-off distance.
