For very high velocities in porous media, inertial effects can also become significant.

Often, porous media contain networks of capillaries, much like a sponge.

It is a generalisation of the Reynolds number for flow through porous media.

The fundamental processes are all related to the behaviour of porous media.

Ideal for porous media flow coupled to other physics such as poroelasticity applications.

Tortuosity is commonly used to describe diffusion in porous media, such as soils and snow.

Permeability measures the ability of fluids to flow through rock (or other porous media).

You may also check text books on "heat transfer in porous (or multiphase) media."

Many of their important properties can only be rationalized by considering them to be porous media.

Fluid flow through porous media is a subject of most common interest and has emerged a separate field of study.
