kapillärstrukturen
Kapillärstrukturen, often referred to as capillary structures, are a fascinating aspect of fluid dynamics and porous media. They describe the behavior of liquids within narrow tubes or porous materials where surface tension forces become dominant over gravitational forces. These structures are characterized by the small diameter of the channels, typically on the order of micrometers or nanometers.
The core principle behind capillary structures is the interplay between adhesion and cohesion. Adhesion is the
Conversely, if cohesion is stronger, the liquid may be repelled by the surface, leading to capillary depression.
