Experimental Study on Liquid Streaming by SAW

Water streaming on the surface of SAW propagating substrate is called SAW streaming. The mechanism of ultrasonic radiation into water due to mode conversion from SAW and the acoustic streaming caused by the sound waves are discussed. The SAW streaming pattern is observed on a metallized surface of SAW propagation. Fundamental experiments for the application of SAW streaming to fluid devices are carried out, and fluid pump and guide are demonstrated.
