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.

利用国际空间站上的日本实验舱Kibo成功地进行了一系列液桥中Marangoni对流的微重力实验。液桥的纵横比变化范围很广，即：即，测试了在地面上无法实现的高径比。得到了不同尖点比和普朗特数下，从定常流到振荡流转变的临界Marangoni数。此外，还进行了半球形液滴的微流体力学实验，其中表面张力起着至关重要的作用。
