kapillærgennemstrømningen
Kapillærgennemstrømningen, also known as capillary flow, refers to the movement of liquids through narrow channels or porous materials driven by capillary forces. These forces arise from the interplay between adhesive forces between the liquid and the solid surface, and cohesive forces within the liquid itself. When the adhesive forces are stronger than the cohesive forces, the liquid will tend to wet the surface and rise or spread within the capillary.
The phenomenon is governed by the Young-Laplace equation, which relates the capillary pressure to the surface
Capillary flow is a fundamental process observed in a wide range of natural and technological applications.
In materials science and engineering, capillary flow is exploited in processes such as ink-jet printing, where
