抄録
Microgravity pool boiling experiments were carried out, utilizing a drop shaft at the Japan Microgravity Center, which enables control of microgravity to within one ten-thousandth of terrestrial gravity for a period of 10 seconds. Vapor bubbles were generated on a Joule heated ITO film plated on a thin glass or alumina substrate, which was immersed in a pool of saturated liquid at atmospheric pressure. The critical heat flux to CFC-113 was lowered, in microgravity, to one-fifth of that achieved under the normal terrestrial condition. In contrast, the critical heat flux to water was not reduced below one-half due to the reduction of gravity. This difference in the critical heat flux values is presumably ascribable to the difference in the frequency of bubble departure from the heater surface between CFC-13 and water, which is dependent on the difference in thermophysical properties, especially the surface tension and the heat of vaporization, between the two fluids.
