Abstract: Numerical simulation of an ultrasonic levitated droplet shape is discussed. In the circumstances of acoustic standing wave, water droplets are trapped at the sound pressure node from the effect of the acoustic radiation force, that is, a static force generated because of acoustic nonlinearity. While trapped near the node, the droplets are experimentally known to change their shapes into spheroid, though, very few report has numerically calculated the shape of the droplet considering the free surface boundary of the droplet. In this report, authors successfully simulate the two-dimensional shape of the droplet using distributed point source method (DPSM) and moving particle semi-implicit (MPS) method.
