Transient flow through porous mediums

Journal of Geophysical Research, 1965
One-dimensional transient seepage problems are analyzed. This one-dimensional approach may be considered as an approximation to the two-dimensional problem, i.e., flow from a basin of rectangular cross section having a large ratio of width to depth. Mathematically, the problem involves a free boundary value problem of potential theory; it is nonlinear.

The Porous Medium Equation

2006
Abstract The heat equation is one of the three classical linear partial differential equations of second order that form the basis of any elementary introduction to the area of PDEs, and only recently has it come to be fairly well understood.

Diffusion Through a Porous Medium

1973
The principal object of this chapter is the estimation of the effective diffusion coefficient D e of a solute in a gaseous or liquid mixture when the mixture is in the presence of a suspended solid phase. Bounds on D e are calculated for an isotropic suspension whose only known statistical property is the void fraction, these are rigorously shown to be

Permeability of Orthotropic Porous Mediums

Water Resources Research, 1968
The mathematical definition of permeability for orthotropic porous mediums is developed from the assumption that orthotropic porous mediums (i.e., porous mediums that possess three mutually perpendicular planes of structural symmetry) obey Darcy's Law in the three directions normal to the planes of symmetry.
