Abstract: To study the working mechanism of a high-efficiency hydrodynamic cavitation generator,the irregular cavitation patterns of a rotor-stator centrifugal hydrodynamic cavitation generator were investigated by experimental test and numerical simulation. The simulation result agrees well with the test result. It was found that three different cavitation mechanisms exist in the cavitation generator: blunt body cavitation,trailing vortex cavitation,and wedge grooved cavitation,which were located at the ... More
