Enhanced Heat Transfer

Condensation can be enhanced by using micro/nanostructured surfaces. However, no surface was able to avoid the flooding-induced condensation heat transfer deterioration at high ΔTsub (the degree to which the condenser surface is cooled relative to the surrounding vapor). Here, we propose a brand-new three-dimensional (3D) hybrid surface to prevent the condensation surface from flooding.
