A major problem with cavitation in pumps and other hydraulic devices is that there is no effective method for detecting … or predicting its inception. The traditional approach is to declare the pump in cavitation when the total head pressure … already cavitating at this point. A method is needed in which cavitation events are captured as they occur and characterized …

the present study, an alternative technology based on cavitation jets is suggested. It is found that jets can separate … bitumen at low temperatures (5-6 °C) and cavitation jet technologies have the potential to replace hydrotransport. A series of … nozzles were designed for low intensity cavitation at high cavitation numbers (σ=0.37 - 0.46) to test different types of …
