Abstract :
Fluid motion due to high intensity sound is known as acoustic streaming. These flows are generated around obstacles immersed in sound or near oscillating bodies. Boundary streamings occur near the surface of a body in a sound field. In particular, streaming excited by SAW (surface acoustic waves) results in a slender jet. We investigated this streaming theoretically and experimentally. We applied the acoustic streaming theory and SAW transfer theory to the streaming excited by SAW
