Abstract

Stationary movement of a bubble in a cylinder container have been analyzed with Eulerian coordinate expression. The results calculated were compared with several experimental data, and the size effect of container was estimated for the future works. Introduction When any liquid material solidifies under the micro gravity circumstance, bub- bles are sometimes harmful to the material solidified. Though it is difficult to remove bubbles from the liquid material by using the buoyancy, a bubble motion in a liquid material driven by the Marangoni convection is useful for removing itself under the micro gravity. Although the fluid experiment under the micro-gravity can be carried out on the ground, e.g. in th
