The Parameters of the Disordered Nanoporous Medium

An approach has been proposed for the analysis of transition of a non-wetting liquid to clusters of liquid in the disordered nanoporous medium. This approach describes a novel model of randomly distributed overlapping spheres of different radii. The model allows to define the disordered porous medium with new parameters: the number of nearest neighbors and the area of all mouths that connect pore with the neighboring pores. These parameters depend on the pore size and porosity and make it possible to analytically describe the dispersion transition.
