| Popis: | It is expected to manufacture new materials with containerless processing under the micro-gravity environment in space. In order to achieve the containerless processing, it is necessary to levitate a large droplet. 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 and its internal 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 flow of the levitated droplet in space. 資料番号: AA0063349041 |
