On modeling, simulation and statistical properties of realistic three dimensional porous networks

The basis for modeling and simulation of self-consistent porous networks en compassing pore and throat-size distributions, size correlation and non-uni form connectivity are given. The framework is a straightforward generalizat ion of the Dual Site-Bond Description (DD) of Ref. (J. Chem. Soc. Faraday T rans I 84, 801 (1988)), which considers heterogeneity (size distribution of entities), correlation and connectivity as interdependent characteristics of the porous space. A general and technically simple method for Monte Carl o simulation of three-dimensional networks is presented and exemplified. St atistical and topological properties of simulated networks are shown and an alyzed.
