Some fractal characters of porous media
WebFeb 1, 2012 · 1. Introduction. For porous metal materials, the shape and distribution of pore are similar in the microstructure to pores' in sandstone on earth and the pore-structure usually exhibits fractal character [1].Pore-structure is one of important factors to affect the properties of porous metal materials, but it is very difficult to describe the pore-structure … WebIn addition, the present work reveals that the relative permeability depends not only on saturation but also on the two fractal dimensions, pore fractal dimension (at porosity …
