Phenomena of transport in porous media are encountered in many engineering disciplines. Civil engineering deals, for example, with the flow of water in aquifers, the movement of moisture through and under engineering structures, transport of pollutants in aquifers and the propagation of stresses under foundations of structures.

POROUS MEDIUM MAGNETOHYDRODYNAMICS
Acta Mathematica Scientia, 1982Abstract here we established the mathematical model of dynamics of porous solid medium saturated with compressible magneto-fluid, directly coupled the stress, flow and electromagnetic fields, studied their interactions and propagation regularity of waves and proved that there exist various P and S waves and also their mixture, which, generally ...

Convection Currents in a Porous Medium
Journal of Applied Physics, 1945The problem is considered of the convection of a fluid through a permeable medium as the result of a vertical temperature-gradient, the medium being in the shape of a flat layer bounded above and below by perfectly conducting media. It appears that the minimum temperature-gradient for which convection can occur is approximately 4π2h2μ/kgρ0α D2, where ...

Since marine mud supports shear waves, it must have an elastic, though fragile, frame. It is also saturated with seawater, therefore it could be modeled as a porous medium. It is an unusual porous medium for a number of reasons. The boundary between the skeletal frame and the pore fluid is difficult to define.

DISPERSION IN HIGH-POROSITY POROUS MEDIUM
Journal of Porous Media, 2023In this study, the behavior of flow and transport through a high-porosity porous medium is investigated numerically. Steady-state, 2D Navier-Stokes and transient advection-diffusion equations are solved numerically to simulate water flow and tracer transport in an artificial porous medium.

Capillary Condensation in a Fractal Porous Medium
Physical Review Letters, 2001Small-angle x-ray and neutron scattering are used to characterize the surface roughness and porosity of a natural rock which are described over three decades in length scales and over nine decades in scattered intensities by a surface fractal dimension D = 2.68+/-0.03.

Filtration Combustion in Wet Porous Medium
SIAM Journal on Applied Mathematics, 2009We consider the filtration combustion for configuration where air is injected behind the wave into a porous medium containing a solid fuel. The simplest flow contains planar combustion and thermal waves, each propagating with its own speed. In this work, we study such a flow, in the case where the porous medium contains initially also some amount of ...

The soil is the upper layer of the unsaturated zone of the earth. Soils are very diverse in composition and behavior. The solid phase consists of mineral particles of various sizes and shapes and organic matter in various stages of degradation. Plant roots and the living soil population complete the system.
