WebMay 31, 2024 · The profile of capillary bridges between two vertically stacked cylindrical fibers/monofilaments were predicted via an interactive finite-element program known as Surface Evolver. It is a public domain finite-element package developed by Ken Brakke for simulation of interfaces restricted by energies and the Laplace pressure [41]. WebFeb 27, 2024 · Capillary imbibition is a mechanism that plays a significant role during rehydration of dry food particles that are considered as porous media. Imbibition is highly dependent on the wettability of the porous …
WebWhen the surface/interface elasticity is overlooked, the elastic deformation of a semi-infinite substrate caused by a cap-shaped droplet is calculated analytically through a new approach in which the deformed wetting interface is approximately taken as a rotational ellipsoid surface. WebApr 12, 2024 · The surface tension of water is 0.072 N m −1 . We find that surface tension forces are significant for the straight extensions of the barbules in the inner zone as well as for the barb shafts and barbules in the outer zone; their lengths are 2–18 times their elasto-capillary lengths.

WebA small drop of water lying on a flat surface offers a familiar example of capillary surface. More generally, we call capillary surface the interface between two fluids that are in contact with each other without mixing. The shape of such surfaces is mainly determined by the phenomenon of surface tension, which results from
