In water-scarce regions, passive dew collectors may serve as vital supplementary water sources by collecting dew and rainwater, especially in arid or semi-arid African areas. This study examined enhancements to the standard passive dew collectors through a field experiment, which includes modification such as increased surface roughness through sandblasting (25 % coverage), adjusting panel geometry with sharp edges, and adding five cotton wires on the condensing surface. The dew was collected through gravity induced collection method, meaning it was not scraped from the panels.

几何形状和表面处理对被动露水和雨水收集的影响


在缺水地区，被动式露水收集器可以通过收集露水和雨水作为重要的补充水源，特别是在干旱或半干旱的非洲地区。这项研究通过现场实验检验了标准被动露水收集器的增强功能，其中包括修改，例如通过喷砂（25％覆盖率）增加表面粗糙度，调整具有锋利边缘的面板几何形状，以及在冷凝表面上添加五根棉线。露水是通过重力感应收集方法收集的，这意味着它不是从面板上刮下来的。
