Abstract

Assuming that vapor adsorption plays a major role during dropwise condensation

a physical model based on the coexistence of drops and film has been developed. A heat transfer coefficient correlation was derived by theoretical analysis. The comparison between theoretical calculation and experimental results of the heat transfer coefficient was quite satisfactory. The calculated results indicated that heat was mainly transferred through microdrops and the film region. The film accounted for about 15%-25% of the total area and accounted ior about 85%-95% of the total heat energy transferred.
