Abstract The aim of this paper is to review the numerical simulation methods now being used for dealing with fluid displacement in porous media. One of them is the invasion percolation method, IP, which applies where capillary forces are dominant with respect to viscous forces at the fluid interface.

Laminar isothermal fluid flow of two immiscible compressible fluid phases in a porous medium is formulated in terms of four unknown functions $\rho _1$, $\rho _2$, $S_1$ and $S_2$ in a pair of partial differential equations \[ \frac{\partial } {{\partial t}}\left[ {\phi (x,t)S_i \rho _i } \right] = \frac{\partial } {{\partial x}}\left\{ {\kappa (x,t ...

Combustion Fronts in Porous Media
SIAM Journal on Applied Mathematics, 2002Summary: The equations governing combustion in situ in petroleum reservoirs are cast in a way that is appropriate to the study of the time asymptotic fundamental waves: rarefactions and shocks. The physical diffusion terms are maintained so that the internal structure of shocks can be analyzed.

Nature, 1961
THE tortuosity, T, of a porous medium such as sandstone is a quantity that has been interpreted in various and sometimes conflicting ways, particularly its relation to porosity, ϕ, and formation factor, F (refs. 1–4). Tortuosity originally was understood to mean the square of the quotient average length of a flow-line divided by the net distance ...

Capillary rise in porous media
Physica A: Statistical Mechanics and its Applications, 2001Capillary rise experiments were performed in columns filled with glass beads and Berea sandstones, using visual methods to register the advance of the water front. For the glass bead filled columns, early time data are well fitted by the Washburn equation. However, in the experiments, the advancing front exceeded the predicted equilibrium height.

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.
