Theories and theoretical models for percolation and permeability in multiphase systems: comparative analysis

The terminology and the physical sense of percolation and permeability were analyzed. Existing theories of percolation and permeability were analytically compared with respect to their applicability and effectiveness. It is concluded that the main tendency in the development of the concept of percolation/permeability consists in the fundamental investigation of the relationship between the preparation conditions of the solid, its structural characteristics and measured properties — not only percolation/permeability but also adsorption, Hg-intrusion, etc.
