表面超疏水性能的数值模拟研究进展

表面超疏水是自然界中一种常见的极端润湿现象。一般认为,表面超疏水是由表面微观结构和化学成分共同决定的。超疏水表面由于独特的非润湿性能,在润湿性变化、减阻、液滴弹跳、传热、蒸发、冷凝等方面具有广泛的应用前景。总结了近年来研究人员在超疏水表面润湿性变化、减阻、液滴弹跳、传热、蒸发、冷凝等方面的数值模拟研究情况,归纳了在超疏水性能研究中常用的数值模拟方法,并对其进行了评价,指出了这些方法存在的优点和缺点,提出了超疏水性能数值模拟研究应该关注的重点和研究方向。

Research Progress in Numerical Simulation of Surface Superhydrophobic Properties

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.
