Ultrasonic Properties Effects on Gas Bubble Radial Oscillations in Liquids

A detailed analysis is provided to discuss the effects of acoustic driving frequency and amplitude on bubble radial oscillation based on a revised bubble dynamical model. Numerical study demonstrates that 3 types of bubble radial oscillation can be achieved according to different driving signal frequency; driving signal amplitude affects oscillation differently due to its value, and a certain critical value of acoustic signal amplitude was found where the oscillation is becoming chaotic.
