When ultrasound generated in liquid is focused around the interface between the liquid and air, the liquid is lifted by ultrasound, and a drop chain emerges from the interface. After the emergence of a drop chain, sometimes minute droplets are scattered from the surface of it. The phenomenon is called ultrasonic atomization. Two hypotheses of the atomization mechanism have been proposed; one is contribution of the oscillation and collapse of cavitation bubbles, and the other is capillary wave caused by instability of the surface. In this paper, highspeed photographs of drop chains induced by ultrasound at 1 - 3 MHz were taken, and the oscillation of capillary wave before the atomization was analyzed. |
