Considering liquid viscosity, surface tension, liquid compressibility and turbulence, the dynamical behaviors of cavitation bubble in venturi cavitation reactor are numerically investigated with using acoustic field regarding water as a work medium. The effects of acoustic frequency, acoustic pressure and ratio of throat to pipe diameter on cavitation bubble dynamics, bubble temperature and pressure pulse by rapid collapse of cavitation bubble are analysed. The results show that bubble motion of hydrodynamic cavitation modulated by ultrasound, becomes the high energy stable cavitation. It is favorable for enhancing the cavitation effect.
