Verification of Darcy's Law

Great Rivers History, 2009
First-year engineering students at Virginia Tech are required to take an introduction to engineering course, EngE 1024 Engineering Exploration, in their first semester. One major objective of the course is to introduce the students to basic engineering principles and skills using hands-on projects.

On a possible extension of Darcys law

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1974
Abstract A method of obtaining a first order approximation to the equations governing the motion of flow through a porous medium under non-isothermal conditions is suggested. The method starts with the governing microscopic equations of flow in the pores and averages these equations over a small volume to get the equations in terms of macroscopic ...

WEAK NONLINEAR CORRECTIONS FOR DARCY’S LAW

Mathematical Models and Methods in Applied Sciences, 1996
We consider the Navier-Stokes system in a periodic porous medium Ωε where ε is the characteristic pore size. The viscosity is of order εβ with 0≤β<3/2, sufficiently close to the critical exponent β=3/2. An asymptotic expansion for the velocity and the pressure, in terms of the local Reynolds number Reε=ε3−2βis set and a second-order error estimate ...

Darcy’s Law

1970
In this chapter the fundamental law for the description of the movement of groundwater through a soil is considered in its most simple form. Some aspects of the basic parameter, the coefficient of permeability, are discussed from a physical viewpoint.

Thermodynamic Analysis of the Darcy Law

Journal of Applied Mechanics, 1961
The Darcy law is used extensively to describe the flow of fluids through porous media. According to this law the fluid flow is linearly dependent upon the pressure gradient and the gravitational force. The proportionality factor is generally known as the permeability of the porous medium.

Darcy's Law for a Heterogeneous Porous Medium

Journal of Porous Media, 2001
Summary: We consider slow flow of Newtonian fluid through a spatially varying porous medium. Applying the method of homogenization to a heterogeneous porous medium possessing a microscopic locally periodic structure, we are able to derive an appropriate form of Darcy's law.
