Abstract :
In order to examine the dynamics characteristic of cavitation bubble in terms of different dynamics parameter of radius and volume respectively. So we consider the dynamics factor of viscosity, the surface tension, the vapour pressure and the adiabatic compress. To use the Gear Stiff algorithm to simulate the famous traditional Rayleigh-Plesset equation in terms of radius frame and use the Runge-Kutta algorithm to simulate the Rayleigh-Plesset equation in terms of volume frame derived by T. G. Leighton according to the Navier-Stokes equation and other conditions. Based above conditions, we discuss the influence of different simulation modeling dynamics characteristic by change the ultrasonic pressure amplitude, bubble radius or volume and ultrasonic frequency. The simulation research of the two different dynamics parameter of Rayleigh-Plesset modeling indicate that the results have the resemble variety tendency and the two model may be used to research the ultrasonic cavitation bubble dynamics. The results also supply the different research ways of cavitation bubble dynamics and the theory base of practice engineer applications of ultrasonic cavitation effect.
