| Abstract(in English) | Ultrasonic droplet levitation has recently been drawing attention as a way of non-contact transportation. Many experiment revealed that the shape changes or streaming field on the levitating droplets, however, quite small number of numerical simulation have discussed this phenomenon including fluid dynamics within the droplet. In this paper, the driving force distributions inside the viscous boundary layer just above the drplet surface are discussed, expecting a force input for the coupled analysis using distributed point source method (DPSM) and moving particle semi-implicit (MPS) methodto calculate rotating or internal streaming on the droplet. Because Reynolds stress on the droplet surface depends on the viscosity of air, acoustic DPSM is extended to handle the boundary layer approximation to calculate the steep change of particle velocity within the layer. |
