Surface Disintegration and Atomization of Micro Water Droplet Subjected to Surface Acoustic Wave

抄録

This paper concerned with the process of liquid atomization. The dynamic behavior of water droplet subject to surface acoustic wave was observed using a high speed video camera system. Liquid was disintegrated into fine liquid particles by the action of surface acoustic wave. The process of bursting phenomena of water droplet was revealed experimentally. Furthermore, the effect of micro solid particles in water droplet on bursting phenomena was investigated. Small spherical styrene particle was used as solid particle in the experiment. It was found that the dispersion time of water droplet was delayed by the solid particles in the water droplet. The dispersion time of droplet depended on the number of solid particles.
