The Twenty-second Space Utilization Symposium (January 17-19, 2006: Science Council of Japan, Roppongi, Tokyo, Japan)

The experimental study on Marangoni flow in half-zone liquid bridge of silver melt was carried out. Use of silver melt as a representative of low-Prandtl number fluid has the following merits; It is easy to lower the Marangoni number due to its thermophysical property. Solubility of oxygen in silver melt is sufficiently high and an oxide film is not formed at the melt surface under the atmospheric condition. Using a molten silver bridge, the Marangoni number of as small as Ma = 160 was obtained and an oscillatory flow with frequency of f = 0.26 Hz was observed.
