| Abstract: | The dynamic model of a cavitation bubble in ultrasound field in liquid was established according to the analysis of thermodynamics and kinetics. The model equation was solved and the cavitation process was simulated, where the factors including the ultrasonic pressure amplitude, frequency, the initial bubble radius, the density of the liquid, the surface tension, dynamic viscosity were discussed. |
