ABSTRACT
A porous medium, that is a material including voids, is by definition a binary system, made of two components, the solid phase and the pore (void) phase. This chapter explains the pore solid fractal (PSF) model, which is explicitly a three-phase model of porous media, and discusses its contribution to the concepts of key scaling properties in fractal porous media. It presents work done on PSF model, and methodological discussions derived from fluid flow type of modeling point of view of a porous medium. The chapter presents relevant properties of the PSF model, which can be mathematically derived. It simulates the capillary pressure curve and the permeabilities relative to both fluids, in the unsaturated case as well as in the saturated case which is a particular case of the latter. The chapter addresses the issue of applying the model of real data, namely from images of natural porous media.
