论文摘要
对荒漠化的日益关注，刺激了旨在从露水，雾气和水蒸气等非传统来源获取水的技术研究。一些最有希望的发展集中在改善设计以从雾中收集水。但是，没有共享框架来预测，衡量和比较新原型的水收集效率正在成为该领域进步的主要障碍。我们通过提供一般理论来设计有效的雾气收集器以及一个具体的实验方案来解决这个问题，以提供我们理论的所有必要参数，以量化有效的水收集效率。我们特别表明，高雾收集效率需要多层收集器，并且所有有效的设计都在狭窄的网状孔隙率范围内。我们通过对简单多层竖琴收集器的测量来支持我们的结论。
The growing concerns over desertification have spurred research into technologies aimed at acquiring water from non-traditional sources such as dew, fog, and water vapor. Some of the most promising developments have focused on improving designs to collect water from fog. However, the absence of a shared framework to predict, measure and compare the water collection efficiencies of new prototypes is becoming a major obstacle to progress in the field. We address this problem by providing a general theory to design efficient fog collectors as well as a concrete experimental protocol to furnish our theory with all the necessary parameters to quantify the effective water collection efficiency. We show in particular that multi-layer collectors are required for high fog collection efficiency and that all efficient designs are found within a narrow range of mesh porosity. We support our conclusions with measurements on simple multi-layer harp collectors.
