Power exponential velocity distributions in disordered porous media
Maciej Matyka, Jarosław Gołembiewski, Zbigniew Koza
Velocity distribution functions link the micro- and macro-level theories of fluid flow through porous media. Here we study them for the fluid absolute velocity and its longitudinal…
Anisotropy of flow in stochastically generated porous media
Maciej Matyka, Zbigniew Koza, Jarosław Gołembiewski +2
Models of porous media are often applied to relatively small systems, which leads not only to system-size-dependent results, but also to phenomena that would be absent in larger sy…
How to Calculate Tortuosity Easily?
Maciej Matyka, Zbigniew Koza
Tortuosity is one of the key parameters describing the geometry and transport properties of porous media. It is defined either as an average elongation of fluid paths or as a retar…
Hydraulic tortuosity in arbitrary porous media flow
Artur Duda, Zbigniew Koza, Maciej Matyka
Tortuosity () is a parameter describing an average elongation of fluid streamlines in a porous medium as compared to free flow. In this paper several methods of calculating this…
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…
