Enhanced Thermal Transport of Surfaces with Superhydrophobic Coatings

Abstract

Hydrophobic and superhydrophobic coatings/surfaces are often found in natural systems. These surfaces provide functional advantages, such as self-cleaning and water collection. In this work we show enhanced thermal transport of a copper tube with a superhydrophobic coating. We attribute this enhanced thermal transport to a reduced water layer thickness on the superhydrophobic surface. We used an idealized thermal transport model and showed that the predicted thermal transport rate agreed quantitatively with the observed transport rate and water layer thickness.
