Sinopsis

An experimental investigation was conducted to determine film condensation heat transfer rates under high gravity conditions which were simulated by rotating a cylindrical condensing surface about an axis parallel to its own and lying outside of it. The effective gravitational force was varied from 1g to 80g in several discrete steps. Results indicate that heat transfer rates are proportional to ¼ power of the gravity force but heat transfer rates are higher than predicted by Nusselt's correlation. Such increases in heat transfer rates are explained on the basis of heat transfer enhancement caused by surface waves on the condensate film.
