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.

为了研究悬浮法晶体加工和材料性能测量的关键环节——振荡旋转液滴的特性，对液滴的内外流场进行了数值模拟。通过适当地组合振荡幅度和旋转，可以精确地测量表面张力。液滴表面存在辐射流，液滴周围存在较大的稳定涡，液滴表面存在较薄的流动层。
