Applicability of simplified formulations based on Biot’s theory
Yantu gongcheng xuebao, 2019 Based on the Biot’s theory, three simplified formulations are proposed. The simplifications mainly include neglecting the relative acceleration terms in the dynamic mixture equilibrium equation and the generalized Darcy’s law, neglecting the relative ...

On the validity of modeling concepts for the simulation of groundwater flow in lowland peat areas – case study at the Zegveld experimental field [PDF]
Hydrology and Earth System Sciences, 2011 The groundwater flow models currently used in the western part of The Netherlands and in other similar peaty areas are thought to be a too simplified representation of the hydrological reality. One of the reasons is that, due to the schematization of the

Darcy's law for a compressible thermofluid [PDF]
Asymptotic Analysis, 2008 A linear system of differential equations describing a joint motion of a thermoelastic porous body with a sufficiently large Lamé's constants (absolutelty rigid body) and a thermofluid, occupying porous space, is considered. The rigorous justification, under various conditions imposed on physical parameters, is fulfilled for homogenization procedures ...

Sharp convergence rates for Darcy’s law [PDF]
Communications in Partial Differential Equations, 2022 This paper is concerned with Darcy's law for an incompressible viscous fluid flowing in a porous medium. We establish the sharp $O(\sqrt{\e})$ convergence rate in a periodically perforated and bounded domain in $R^d$ for $d\ge 2$, where $\e$ represents the size of solid obstacles.

Interpretation of macroscale variables in Darcy's law [PDF]
Water Resources Research, 2007 The pursuit of a theoretical foundation of Darcy's law based on volume averaging of equations at the scale of flow in pores has a long history. While theories are well established for homogeneous systems, more complex systems exhibit inconsistencies in the resulting equations.

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid
Advanced Engineering Materials, EarlyView.A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

Advanced Engineering Materials, EarlyView.Geometrical modifications on nitrocellulose membranes can result in observable differences in signal intensity relative to a reference membrane (top and bottom left). Using two reference experiments, we have developed a theoretical model that can reproduce the experimentally observed flow changes and provide information on membrane parameters, e.g ...

Numerical simulation for peristaltic activity of Sutterby fluid with modified Darcy’s law
Results in Physics, 2017 The current work examines the peristaltic flow of Sutterby fluid in a planar symmetric channel. Electrically conducting fluid is considered via imposed magnetic field. An incompressible Sutterby fluid saturates the porous medium. Modified Darcy’s law has
