Abstract

Optimization of the efficiency of the condensers via different surface engineering techniques is a subject of interest due to its wide range of application in thermal management for aerospace vehicles, power generation systems, and etc., which will further result in considerable savings in annual investments and operating costs by millions of dollars. However, the current technologies are lacking either the necessary condensation enhancements or cost-effective, large-scale fabrication method. In this work, we present a new surface topography to enhance drop-wise condensation at low manufacturing costs. These surfaces consist of macro-scale hydrophobic patterns on hydrophilic structures. Due to their high wettability contrast, the biphilic surfaces enhance drop-wise condensation with long-term functionality, and more importantly, they can be easily manufactured in large-scale using conventional methods as no nano- or micro-features are needed.
双亲性表面上的凝结:实验与模拟
通过不同的表面工程技术优化冷凝器的效率是一个令人感兴趣的主题,因为它广泛应用于航空航天飞行器、发电系统等的热管理,这将进一步节省数百万美元的年度投资和运营成本。然而,目前的技术既缺乏必要的冷凝增强,也缺乏成本效益高的大规模制造方法。在这项工作中,我们提出了一种新的表面形貌,以提高低制造成本的滴状冷凝。这些表面由亲水性结构上的宏观疏水图案组成。由于它们的高润湿性对比,双亲性表面增强了具有长期功能的滴状冷凝,更重要的是,它们可以很容易地使用常规方法大规模制造,因为不需要纳米或微特征。
