| Research Abstract |
A series of microgravity experiment of the Marangoni convection in a liquid bridge was performed successfully using the Japanese experimental module Kibo on the International Space Station. The liquid bridges with a wide variety of the aspect ratios, i. e., height to diameter ratios, which cannot be achieved on the ground, were tested. Critical Marangoni numbers of the transition from the steady to the oscillatory flow were obtained for various apect ratios and Prandtl numbers. In addition, hydrodynamic experiment of a hemispherical droplet was made in relation to microhydrodynamics, where the surface tension plays a crucial role.
