Description

Condensation heat transfer is signicant in a variety of industries including desalination, energy conversion, atmospheric water harvesting, and electronics cooling. Recently, superhydrophobic surfaces have gained attention as a possible condensing surface due to their potential for high droplet mobility and coalescence-induced, out-of-plane jumping of the condensate droplets, both of which contribute to higher rates of condensate removal and thus higher thermal transport rates. However, only a limited number of studies have actually measured the rate of heat transfer during condensation on superhydrophobic surfaces. An experimental setup capable of measuring overall heat transfer rates with two independent methods while simultaneously measuring microscale statistics regarding individual drop behavior is constructed and validated against classical equations predicting condensation behavior.
