The Effect of vapor subcooling on film condensation of metals

This work presents an analysis of the interfacial "vapor-condensate" temperature distribution, which includes the effect of subcooling (supersaturation) in the vapor. Experimental data from previous investigators for different metals were analyzed. It is shown that taking into account this subcooling effect permits the thermal interphase resistance to be described with assumption of [sigma] = Constant = 1.0 where[sigma] is the condensation (mass accommodation) coefficient.Sponsored by National Science Foundatio
