Abstract (in Japanese) (See Japanese page) 
(in English) Ultrasonic droplet levitation has recently been drawing attention as a way of non-contact transportation. Many experiment revealed that the levitating droplet changes its shape to spheroid, however, quite small number of numerical simulation have discussed this phenomenon including fluid dynamics within the droplet. In this paper, the coupled analysis using distributed point source method (DPSM) and moving particle semi-implicit (MPS) method is suggested, both of which does not require grids or meshes, therefore, can handle the moving boundary with ease.
The levitating ultrasonic droplet in plane standing wave field between the ultrasonic transducer and the reflector is simulated in this paper. The spheroidal droplets are successfully reproduced numerically, and ratio of the change in spheroidal ratio and the gravitational center position are discussed.
