Abstract

In this paper, we want to research on the superiority of dropwise condensation. First, the concept of interlayer convection was presented. Then, a mathematical model about the transition from film condensation to dropwise condensation was established. It is confirmed in theory that heat transfer coefficients for dropwise condensation are larger than those for film condensation and that the ratio can even be more than an order of magnitude. The effects of the change of drop quantity on the advantage of dropwise convective heat transfer are shown by drawing an instance curve.
