文摘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.
