Research Abstract	In order to study the characteristics of an oscillating-rotating droplet, which is the key point of levitation method for crystal processing and measurement of material properties, inside and outside flow fields of droplet have been simulated numerically. The accurate measurement of surface tension was found to be possible by an appropriate combination of oscillation amplitude and rotation. Radiating flows from the droplet surface, large steady vortices around the droplet, and thin flow layers on the droplet surface were also found.
