Exercises Illustrating Flow in Porous Media
Groundwater, 2001Abstract A set of physically based exercises is described for illustrating concepts and processes related to fluid movement in porous media. These exercises revolve around a permeameter that costs several dollars to construct and requires no external equipment and no electrical power to operate. The exercises can be used to illustrate

Introduction Fluids such as water, steam, petroleum, and natural gas often migrate through the Earth's crust. If these flows occur through open fractures, they can be studied using the channel flow theory developed in Chapter 6. In many cases, however, flows in the Earth's crust occur through a matrix of interconnecting passages provided by large ...

The Interaction of Flow and Reactions in Porous Media
International Symposium on Oilfield Scale, 2003Abstract As water migrates through porous rock, any changes in pressure or temperature, as well as changes in fluid composition, may lead to changes in the solubility of dissolved minerals. We examine the reactions which may develop in such a system, following the injection of water of one temperature and composition into a reservoir ...

Turbulent Flow Through Porous Media
Groundwater, 2001Abstract The pressure driving flow through porous media must be equal to the viscous resistance plus the inertial resistance. Formulas are developed for both the viscous resistance and the inertial resistance. The expression for the coefficient of permeability consists of parameters which describe the characteristics of the porous ...

The study of groundwater and porous media flow has become important during the last years in fields as different as civil engineering, aquifer managing and petroleum engineering. The fundamental equations describing these physical phenomena are well known [5], [6] and before the computers allowed them to be solved numerically, many authors developed ...

On steady stratified flows in porous media
Quarterly of Applied Mathematics, 1982Steady flows of an incompressible and nondiffusive fluid stratified in viscosity and in density that take place in porous media are considered, and conditions necessary for similarity between any two such flows are given with proof. Results on the vorticity and circulation in such flows are also given.

This chapter gives a brief review of the basic equations needed to simulate single-phase and two-phase (oil–water) flow through porous media. It discusses the governing partial-differential equations, their physical interpretation (especially the diffusive nature of pressures and the convective behavior of saturations), spatial discretization with ...

So far our treatment of fluid motions has not emphasized the behavior of fluids residing within porous geological materials. Let us now turn to this topic and, in doing so, make use of our insight regarding purely fluid flows. The general topic of fluid behavior within porous geological materials is an extensive one, forming the heart of such fields as

Stabilization of Flows Through Porous Media
SIAM Journal on Mathematical Analysis, 1979Let $u(x,t)$ be the solution of the Cauchy–Dirichlet problem for the porous media equation in one space dimension in the quarter-plane $(0,\infty ) \times (0,\infty )$. An estimate is obtained for the asymptotic behaviour of $u(t,x)$ as $t \to \infty $, in terms of the prescribed lateral boundary value of u.
