Dropwise condensation (DWC) on non-wetting surfaces has remarkable potential to enhance heat transfer performance compared to filmwise condensation on wetting substrates. In this article, we discuss important recent developments and challenges in the field of DWC, including durability of DWC-promoting coatings, DWC of low surface tension fluids, physical mechanisms governing DWC, unconventional methods to achieve DWC, and promising metrology techniques for DWC. We end the article by providing a road map detailing where we believe the community should direct both fundamental and applied efforts in order to solve the identified century-old challenges that limit DWC implementation.

稳定滴状冷凝的最新发展、挑战和途径：一个观点

与润湿基材上的薄膜状冷凝相比，非润湿表面上的滴状冷凝 (DWC) 具有显着提高传热性能的潜力。在本文中，我们讨论了 DWC 领域的重要最新发展和挑战，包括 DWC 促进涂层的耐久性、低表面张力流体的 DWC、控制 DWC 的物理机制、实现 DWC 的非常规方法以及有前途的 DWC 计量技术。我们通过提供一个路线图来结束本文，详细说明我们认为社区应该在哪些方面指导基础和应用努力，以解决限制 DWC 实施的已确定的百年挑战。
