The theory of flow through fractured rock and homogeneous anisotropic porous media is used to determine when a fractured rock behaves as a continuum. A fractured rock can be said to behave like an equivalent porous medium when (1) there is an insignificant change in the value of the equivalent permeability with a small addition or subtraction to the test volume and (2) an equivalent permeability tensor exists which predicts the correct flux when the direction of a constant gradient is changed… 


The purpose of this study is to determine when a fracture system behaves as a porous medium and when it does, what is the appropriate permeability tensor for the medium. A volume of fractured rock

A Model for Investigating Mechanical Transport in Fracture Networks

A technique is presented to determine when anisotropic fracture systems can be modeled as equivalent porous media (continua) for transport. In order to use the continuum approach, one must

Upscaling of Hydraulic Properties of Fractured Porous Media: Full Permeability Tensor and Continuum Scale Simulations

A novel method based on the utilization of the Delta-Y transformation is introduced for obtaining the effective permeability tensor of a 2D fracture network, which shows that the proposed approach allows for efficient perform upscaling of hydraulic properties by honoring both the underlying physics and details of fracture network connectivity.

Effective permeability of fractured porous media in steady state flow

Flow in fractured porous media was first investigated by Barenblatt and Zheltov [1960] and Barenblatt et al. [1960] by means of the double‐porosity model. A direct, exact, and complete numerical

Numerical Analysis of Unsaturated Seepage Flow in Two-Dimensional Fracture Networks

Abstract Fracture-dominated flow in fractured rocks is of interest in many areas of scientific and technical research. In contrast to the continuum approach, this study employed a discrete fracture

Dependence of Effective Porosity on Fracture Continuity in Fractured Media

Fractured geologic media are typically considered to behave as equivalent porous-media continua for the purposes of hydrologic testing and modeling. The equivalent-continuum effective porosity of a

Thermal convection in three-dimensional fractured porous media.

Results show that the effective approach is not always valid, and that the mismatch between the full calculations and the effective medium approach depends on the fracture density in a crucial way.

Anisotropie Permeability of Fractured Media

The mathematical equivalents of parallel plate openings are used to simulate real fractures dispersed in orientation, distributed in aperture, and of arbitrary spacing. With this idealization of

Validity of cubic law for fluid flow in a deformable rock fracture. Technical information report No. 23

The validity of the cubic law for laminar flow of fluids through open fractures consisting of parallel planar plates has been established by others over a wide range of conditions with apertures

A stochastic‐conceptual analysis of one‐dimensional groundwater flow in nonuniform homogeneous media

The most realistic representation of a naturally occurring porous medium is a stochastic set of macroscopic elements in which the values of the three basic hydrogeologic parameters (hydraulic

The permeability of a sample of an anisotropic porous medium

The directional permeability of an anisotropic porous medium can be defined in two different ways, each yielding a different value for a given set of conditions. Permeability tests on samples

Stochastic analysis of steady state groundwater flow in a bounded domain: 2. Two‐dimensional simulations

A stochastic analysis of two-dimensional steady state groundwater flow in a bounded domain is carried out by using Monte Carlo techniques. The flow domain is divided into a set of square blocks. A

A technique of local averaging is applied to obtain general equations which describe mass and momentum transport in porous media. The averaging is performed without significantly idealizing either

The Theory of Ground-Water Motion

The existing analytical treatments of ground-water flow have mostly been founded upon the erroneous conception, borrowed from the theory of the flow of the ideal frictionless fluids of classical
