Cavitating jet technology can enhance the fluidic effect with the aid of powerful impact force generated by cavitationbubble broken, and can applied to solve engineering problems by means of cavitation effect created by cavitation bubble collapse. Thebrief developing history of research on cavitating jet and the phenomenon is presented, and the characteristics and research status ofcavitation jet and high pressure water jet cleaning technology are compared and analyzed. The formation mechanism and cavitation effectare summarized and discussed, and the applications status of cavitating jet technology in cleaning the decontamination, environmentalchemical engineering, oil production, material crushing and ultrafine grinding and the like are reviewed. In particular, the progress ofcavitating jet technology application at the status quo is expounded. Meanwhile, the development trend and the future research directionof cavitating jet technology are prospected, which provides useful references and research ideas for the further exploration of cavitatingjet mechanism and has a vital guiding significance for extension of its application range.
