Dynamic Study of Water Droplets in Two Phase Liquid by Ultrasound

Abstract

Abstract. In this paper, the dynamic equation of the simplified model of dispersed droplets in two phase liquid under ultrasonic excitation is derived based on the derivation method of cavitation bubble motion equation. The influence of different parameters on the radius of droplet under ultrasonic action is obtained by MATLAB methods. The results show that ultrasonic wave velocity has very little effect on the variation of c radius in different dispersed phase liquid. The smaller the liquid density is, the larger the radius of water-drop grows. The larger the hydrostatic pressure is, the harder the volume of water-drop will change. The theoretical basis for further study on the mechanism of ultrasonic effect on the reverse phase emulsion is established through the exploration of the change of water-drop radius.
