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
