How fast does a droplet flow along a fiber? It depends on the diameter of the fiber... and also on its substructure! These are the findings of a study conducted by researchers who are interested in microfluidics, especially water harvesting in arid/semi-arid regions of our planet.
How fast does a droplet flow along a fiber? It depends on the diameter of the fiber... and also on its substructure! These are the findings of a study conducted by researchers from the University of Liège who are interested in microfluidics, especially water harvesting in arid/semi-arid regions of our planet.
Indeed, what about the behaviour of the droplet in the case where both configurations have the same diameter ? Since the hindrance of the phenomenon is dissipation , one might expect that both cases would yield identical results because the contact surface between the liquid and the fibre is the same."Not at all. We observed that over the same distance travelled, the droplet on the bundle of fibres was faster. It also lost the most volume.
*A moisture farm is an area of land devoted to the production of water by extracting moisture from dry air.Dry, hot regions are difficult places to grow plants because the soil dries out quickly. As a result, farmers in arid and semi-arid regions irrigate their fields with buried networks of irrigation ...
