Research Progress in Numerical Simulation of Surface Superhydrophobic Properties

Abstract

Superhydrophobic surface is a common extreme wetting phenomenon in nature. It is generally believed that superhydrophobic surface is determined by surface microstructure and chemical composition. Due to its unique non - wettability, superhydrophobic surface had a broad application prospect in change of wettability, drag reduction, liquid drop bounce, heat transfer, evaporation, condensation and other aspects. In this paper, the research results of numerical simulations on the change of wettability, drag reduction, droplet bounce, heat transfer, evaporation, condensation of superhydrophobic surfaces in recent years were reported, and then the commonly used numerical simulation methods in the study of superhydrophobic performance were summarized and evaluated. In addition, their advantages and disadvantages were pointed out as well. Finally, the key points and research directions of numerical simulation research on superhydrophobic properties were put forward.
