Background, Motivation and Objective Ultrasonic levitation has recently been drawing attention as a way of non-contact transportation of small objects, such as liquid droplets, in bioengineering and manufacturing industry. The small objects in the finite amplitude sound field have been known to be trapped near the pressure node of the standing wave with the effect of acoustic radiation force. The levitated droplet is reported to turn its shape from sphere to spheroid, and to drive an internal streaming on its surface when they are exposed in the intense sound pressure field. Several analytical reports have mentioned this phenomenon, however, almost no report carried out dynamical simulation on the shape change or internal streaming of the droplet.
