Porous medium

Research output: Chapter in Book/Report/Conference proceedingEntry for encyclopedia/dictionary


A porous medium can be defined as a material which contains spaces which, when continuous in some way, enable the movement of fluids, air and materials of different chemical and physical properties. The ability of a porous medium to permit the movement of fluids, air or a mixture of different fluids is related to porosity and the variability of pore characteristics in that the presence of interconnected pore spaces, and thus permeability properties of the material, enables the movement of fluids and accompanying materials.
