HESS Opinions: Linking Darcy's equation to the linear reservoir [PDF]

Hydrology and Earth System Sciences, 2018
In groundwater hydrology, two simple linear equations exist describing the relation between groundwater flow and the gradient driving it: Darcy's equation and the linear reservoir.

Bioconvective Unsteady Casson Hybrid Nanofluid Flow on a Variable Darcy Regime Between Two Rotating Disks With Variable Heat Source

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study carries significant consequences in various engineering applications, such as cooling rotating disk surfaces, improving chemical reactor performance, and designing filtration systems. Considering these main applications in view, the aim of this study is to investigate time‐dependent Casson hybrid nanofluid flow on a permeable ...

Unsaturated flow characteristics in dual-scale fibre fabrics at one-dimensional constant flow rate

Science and Engineering of Composite Materials, 2016
Fibre fabrics in liquid composite moulding can be considered as dual-scale porous media. In different gap scales, an unsaturated flow is produced during the mould filling process.

No other choice: The fracturing of reflexivity in families' pathways into (non‐)elective home education in England

British Educational Research Journal, EarlyView.
Abstract In England, education is compulsory, but schooling is not: it is legal for families to home educate their children. This form of education is officially termed by the Department for Education as ‘Elective Home Education’. As this designation implies, many families home educate as a positive and preferential ‘choice’.

A 3D FINITE ELEMENT ANALYSIS OF INCOMPRESSIBLE FLUID FLOW AND CONTAMINANT TRANSPORT THROUGH A POROUS LANDFILL [PDF]

Journal of Engineering Science and Technology, 2014
The paper investigated the flow of incompressible fluid and contaminant transport through a Porous Landfill using a numerical technique. A threedimensional finite element analysis technique was adopted for the solution. The problem was based on the Darcy’

Universal Relationship Between Viscous and Inertial Permeability of Geologic Porous Media

Geophysical Research Letters, 2019
Fluid flow through geologic porous media is represented by Darcy's law and its inertial and nonlinear extension, the Forchheimer equation. These relationships equate the product of the driving potential gradient and phenomenological coefficients ...

Study on Non-darcy Seepage Mechanism of Gas Migration in Coal

Meikuang Anquan, 2020
Under different confining pressures, gas seepage tests are carried out, and these tests are used to discuss gas seepage mechanism in coal. The tested and theoretical results show that under different confining pressures, gas seepage laws are consistent ...

ESG Decoupling Phenomenon: A Systematic and Bibliometric Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT ESG decoupling, defined as the gap between a firm's ESG disclosures and its actual practices, poses a critical challenge to corporate sustainability. Using the PRISMA protocol, 451 articles were selected for a comprehensive bibliometric and systematic literature review to map the intellectual structure and thematic evolution of the research on

Greenwashing in the Spotlight: Synthesising Evidence on Unethical Environmental Claims and Future Pathways

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Firms are experiencing mounting pressure to report their environmental impact. Rather than disclosing their actual performance, however, some are engaging in unethical business (i.e., greenwashing) practices. Prior studies have contributed significantly to the greenwashing literature from varied perspectives, but a comprehensive understanding ...

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

Deep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating
