Magnetohydrodynamic flows in porous media
Journal of Fluid Mechanics, 2002The aim of this work is to investigate the tensorial filtration law in rigid porous media for steady-state slow flow of an electrically conducting, incompressible and viscous Newtonian fluid in the presence of a magnetic field. The seepage law under a magnetic field is obtained by upscaling the flow at the pore scale. The macroscopic magnetic field

Simulating flow in porous media
Physical Review A, 1988The problem of two-phase fluid flow in statistically homogeneous but random porous media is addressed. Particular emphasis is placed on the role of the stochastic nature of the porous medium in the development of unstable interfaces at large mobility ratios. A formalism is developed in which the random nature of a real porous medium can be incorporated

Resurgence flows in porous media
Physical Review E, 2009Porous media with resurgences can be described by a double structure, namely, a continuous porous medium and capillaries with impermeable walls which relate distant points of the continuous medium. The resurgences can be either punctual or extended. The equations for flow in such media are derived; some general properties of the resulting system, which

Physical Review E, 1996
The concept of tortuosity of fluid flow in porous media is discussed. A lattice-gas cellular automaton method is applied to solve the flow of a Newtonian uncompressible fluid in a two-dimensional porous substance constructed by randomly placed rectangles of equal size and with unrestricted overlap.

Flow Simulation in Stochastic Porous Media
SIMULATION, 2000A family of gamma distributions can be used to model the pore size distributions in a range of stochastic porous media. Our simu lator generates distributional and net flow data for different fluid flow regimes through such networks. The outputs from the simu lation show strong relationships between mean flow and the variance of pore radii for ...

Coupling Fluid Flow with Porous Media Flow
SIAM Journal on Numerical Analysis, 2002Summary: The transport of substances back and forth between surface water and groundwater is a very serious problem. We study herein the mathematical model of this setting consisting of the Stokes equations in the fluid region coupled with the Darcy equations in the porous medium, coupled across the interface by the Beavers-Joseph-Saffman conditions ...

Annual Review of Fluid Mechanics, 1970
The problems of flow and transport in porous media present many fascinating challenges to students of mechanics: and it is surprising that, over the years, these questions have received relatively little attention at the Congresses and Symposia of IUTAM and of its predecessors.

We now turn our attention to the results that constitute the core of modern research on convective heat and mass transfer through porous media. Our objective is not only to organize the compact presentation of these results, but also to explain their origin.
