It is expected to manufacture new materials with containerless processing under the micro-gravity environment in space. If the levitated droplet is large, the surface of the levitated droplet nonlinearly and dynamically deforms and vibrates in space. In the present working group, nonlinear dynamics of the levitated droplet, surface deformation, its internal flow and the external flow, are experimentally and analytically investigated. The levitation experiments with the ultrasonic levitation apparatus and electrostatic levitation apparatus are conducted under the normal gravity condition and micro-gravity condition with aircraft. Based on the experimental results, theoretical and numerical analyses are conducted to clarify the nonlinear dynamics of the surface deformation, vibration and oscillation, as well as the internal and external flow of the levitated droplet in space. In the present study, new technology to measure the viscosity in high viscosity region is proposed.
