Twofold Description of Percolation in Porous Media

Most porous networks are not merely fully random media: their elements are strongly correlated. A deep reformulation of the original theory of percolation is then undertaken, based on the “Twofold Description” of porous media. This new development renders considerable advantages: (i) the mean- field approximation is exempted in some extent (ii) mean quantities are calculated only at the last stage, concomitantly assuring a greater accuracy of results, and (iii) domain complexions, which constitute a precious information about the state of elements as function of their size, are readily obtained.
