Abstract :
In this work, Flynn´s formulation is adopted to analyze the dynamics, temperature and pressure of the cavitation bubble in the room-temperature liquids (RTIL) because of their unique physical properties. The effects of the ultrasonic intensity, frequency and the initial radius of the bubble on the cavitation process are studied, and the temperature and pressure in the collapsing bubbles are also analyzed. It is found that the intensity of cavitation increases remarkably with the increase of the bulk solution temperature.
