| Outline of Final Research Achievements |
Numerical simulations of levitated rotating droplets are performed, and the shape variation and internal flow field are studied for the development of measurement technique of high-temperature molten material properties. The relationship between the deformation of asymmetric droplet and rotation rate agrees well with the existing experimental result. It is found that the internal stress field is asymmetric due to the circulating flow formed by the deformation.
