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., 形態: カラー図版あり, 資料番号: AA0064297122}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {浮遊液滴非線形ダイナミクスワーキンググループ活動報告}, volume = {25}, year = {2009} }
