Finite-size anisotropy in statistically uniform porous media
Zbigniew Koza, Maciej Matyka, Arzhang Khalili
Anisotropy of the permeability tensor in statistically uniform porous media of sizes used in typical computer simulations is studied. Although such systems are assumed to be isotro…

Tortuosity-porosity relation in the porous media flow
Maciej Matyka, Arzhang Khalili, Zbigniew Koza
We study numerically the tortuosity--porosity relation in a microscopic model of a porous medium arranged as a collectin of freely overlapping squares. It is demonstrated that the…
