Abstract

Recent in vitro and in vivo experiments have demonstrated that sonochemical reactions can be greatly accelerated when the second harmonic is superimposed on the ultrasonic field. The effect of second-harmonic superimposition on the rectified diffusion through the gas-liquid interface of cavitated micro bubbles is theoretically estimated. The theory approximately explains the dependence of the in vitro sonochemical reaction rate on the combination of the fundamental and the second-harmonic amplitudes.
