Chapter 4 Reports on Marangoni Experiments in Space (MEIS) - Correlation between G-jitter and liquid bridge -

Fac. Science & Technology, Tokyo University of ScienceDept. Mechanical Engineering, Ichiro UENO

ABSTRACT Marangoni Experiments in Space, 'MEIS,' has been carried out on Japanese Experimental Module, 'Kibo,' aboard the International Space Station (ISS) since August in 2008. Researchers on MEIS has been focusing on detecting transitions of the flows induced by thermocapillary effect in a half-zone liquid bridge, and on unique behaviors of the suspended particles in the bridge. The researchers has experienced significant deformations of the liquid bridge due to the jitter of the gravity (G-jitter, so called) on the ISS through the experiments. The dynamic behaviors of the liquid bridge of 30 mm or 50 mm in diameter are briefly introduced in this chapter.
