In order to find the best coupling effect, the effects of some parameters for double ultrasound cavitation dynamics are studied. The Rayleigh-Plesset equation model is modified and the numerical result is obtained by using the Runge-Kutta algorithm provided by MATLAB software. Effects of cavitation bubble dynamic driven by double ultrasound under different coupling conditions like frequency, phase difference and ultrasonic intensity are investigated. The results show that the double ultrasound could, under ...
