Research Abstract

An acoustic streaming is occurred in a droplet on a surface acoustic wave (SAW) propagating surface The aim of this research is to clarify phenomena in the droplet based on the observations and to explain those using finite element method. Using a high-speed camera, we succeeded to observe the acoustic streaming in a droplet. When the droplet is not manipulated, stable streaming was observed. When the droplet is manipulated, an acoustic pressure force acts to the tip of it and that is extended. However, SAW incident side of droplet is not deformed. When the acoustic pressure force is larger than binding force, incident side of the droplet is dragged and then the droplet is manipulated. Droplet surface is changed during droplet manipulation. To simulate of the droplet manipulation, we must consider free boundary model for the calculation. It is difficult to introduce the free boundary model into our calculation method. This is our future work.
