Harvesting Fog Can Provide Fresh Water in Desert Regions

Caption

(a) Simulation of flow past a cylinder with inertial particles by Chan, tracking the impact of particles on the surface of the collector. (b) In simulations, tracking a single droplet trajectory elicit that particle collides (red) when lubrication interaction is neglected, and skids along the surface when lubrication effect is present (blue). (c) Similar dynamics with lubrication is observed in experiments conducted by Shahrokhian, where particle barely touches and escapes from being deposited on the collector. (d) Three-dimensional simulation inertial particles flowing past a sphere with small bumps, mimicking surface features of Namib beetles.
