Summary

The critical heat fluxes for both n-pentane and R113 under the reduced gravity were lowered to about 40% of the corresponding terrestrial values. Although the heat transfer characteristics in a low heat flux nucleate boiling regime for both n-pentane and R113 showed no more than a slight change with the reduction in gravity, a significant heat transfer deterioration was noted with water in the reduced gravity boiling. This particular difference in the gravity dependency of heat transfer was ascribed to a considerable difference, between the organic fluids and water, in the behaviour of attachment to the heater surface of the bubbles grown up, while the behaviour of attachment must depend on the surface tension of each fluid and the wettability of the heater surface with the fluid.
