论文摘要
对固体表面的润湿性进行图案是一种成功的策略，以控制蒸气在部分润湿的固体表面上的滴水凝结。我们跟随水蒸气与结构化的共平面电极的电解官能化表面。对数百万滴的实验分布的详细分析表明，尽管存在接触角滞后和随机跌落合并事件的发生，但优先的下降位置紧随数值计算得出的滴度滴度依赖性静电能量的局部最小值的演变，这是在二维中的。即使是竞争优先位置之间的微妙过渡也是该模型正确重现的。基于对冷凝模式的定量理解，我们讨论了一系列重要的后续步骤，这些步骤需要采取这些步骤，以证明在各种应用中，尤其是针对增强热传递的各种应用中的可靠绩效增长。
Patterning the wettability of solid surfaces is a successful strategy to control the dropwise condensation of vapor onto partially wetting solid surfaces. We followed the condensation of water vapor onto electrowetting-functionalized surfaces with structured co-planar electrodes. A detailed analysis of the experimental distribution of millions of drops reveals that despite the presence of contact angle hysteresis and the occurrence of random drop coalescence events, the preferential drop position closely follows the evolution of the local minima of the numerically calculated drop size-dependent electrostatic energy landscape in two dimensions. Even subtle transitions between competing preferred locations are properly reproduced by the model. Based on this quantitative understanding of the condensation patterns, we discuss a series of important follow-up steps that need to be taken to demonstrate a reliable performance gain in various applications focusing in particular on enhanced heat transfer.
