Limit of Anisotropic Hydraulic Conductivity Ratio of Homogeneous Granular Materials

This paper presents a theoretical upper limit for the anisotropic hydraulic conductivity ratio of homogeneous granular materials with internal structure. On the basis of a volume averaging approach, a theoretical analysis is proposed to relate the permeability of granular material to the spatial distribution of pore spaces. For flow in granular materials, both the linear porosity in the flow direction and the areal porosity in the plane …
