In order to study the influence of solid-liquid interfacial energy on the filmwise condensation heat transfer performance

a correlation relating heat transfer coefficient with contact angle was derived with respect to liquid film flow and heat transfer at vapor-liquid interface. The calculated results for steam filmwise condensation indicated that heat transfer coefficient increased with increasing contact angle when the contact angle was within a certain range. When contact angle was very small (approaching 0°)

the predicted heat transfer coefficient was consistent with the result of classic Nusselt theory.
