Consolidation of Porous Media with Non-Darcy Flow

Journal of the Engineering Mechanics Division, 1973
A nonlinear quasi-static theory of one-dimensional consolidation accounting for non-Darcy fluid flow is presented. A specific boundary value problem is examined with the physics being examined in detail. Using a similarity variable, an exact early-time solution is developed. An approximate long-time solution is obtained by assuming a trial solution and

JEFFERY-HAMEL FLOW IN CONDUCTING NANOFLUID: NON-DARCY MODEL

Nanoscience and Technology: An International Journal, 2023
The Jeffery-Hamel flow of magnetized nanoparticles saturated with porous matrix is inspected. Nanotechnology has provided exciting new materials for enhancing engineering devices, including electromagnetic permeable nanofluids. The Darcy-Forchheimer model is employed to define the porous medium.

A Criterion for Non-Darcy Flow in Porous Media

Transport in Porous Media, 2006
Non-Darcy behavior is important for describing fluid flow in porous media in situations where high velocity occurs. A criterion to identify the beginning of non-Darcy flow is needed. Two types of criteria, the Reynolds number and the Forchheimer number, have been used in the past for identifying the beginning of non-Darcy flow.

Identification of non‐Darcy groundwater flow parameters

International Journal for Numerical Methods in Fluids, 1988
AbstractNon‐Darcy groundwater flow parameters are identified for three different flow systems. In the first system, which is essentially one‐dimensional, the parameters are determined by means of an integral method. A rectangular parametric grid is used for the identification of the non‐Darcy friction coefficients in the second system, which is two ...

Prediction of Non-Darcy Flow in Porous Media

Journal of the Irrigation and Drainage Division, 1979
Equations were derived that facilitate prediction of both the onset of non-Darcy flow in a porous medium, and the viscous and inertia force fractions of the hydraulic gradient, dp/ds, after non-Darcy flow has begun. The equations are based on measurements of hydraulic gradients dp/ds and corresponding fluxes q carried out with a permeameter in both the

An Approximate Method for Non -Darcy Radial Gas Flow

Society of Petroleum Engineers Journal, 1964
Abstract Approximate analytical solutions for non-Darcy radial gas flow are derived for bounded and infinite reservoirs producing at either constant rate or constant pressure. These analytical solutions are compared with published results for non-Darcy flow obtained on digital and analogue computers, and the agreement is shown to be very

Temperature effects on non-Darcy flow of compacted clay

Applied Clay Science, 2017
Abstract Due to biochemical reactions that can occur inside the landfills, accumulation and diffusion of the heat generated by the reaction can changes of internal temperature of landfills. The internal temperature can reaches 55 °C to 60 °C. The hydraulic conductivity and threshold gradient of clay liner could be affected by this high temperature ...

Analytical Treatment of Transient Non-Darcy Flow

SPE Annual Technical Conference and Exhibition, 1991
Abstract Non-Darcy flow is an important factor affecting deliverability of gas and high-rate oil wells. An analytical model describing the transient non-Darcy flow is designed. The model is used to define a better interpretation approach.

Non-Darcy Flow Through Fibrous Porous Media

Journal of Applied Mechanics, 1969
Experiments are performed to explore the flow characteristics of porous media having the form of a latticework of metallic fibers. Five such media are investigated, four among which share the characteristic that there are no free fiber ends within the medium.

Modeling of Non-Darcy Flow Through Porous Media

SPE Reservoir Simulation Symposium, 1997
Abstract Darcy's law is inadequate for describing high-velocity gas flow in porous media, which occurs in the near wellbore region of high capacity gas and condensate reservoirs. This study is directed at understanding the non-Darcy flow behavior.
