Grouting Mechanism of Cement Slurry in Porous Media Based on Large‐Scale Model Test

Advance in Civil Engineering
The filtration effect of slurry particles in the grouting of dense porous media may lead to a big difference between the theory and engineering practice.

Water flow through tailings dams [PDF]

, 1993
Water levels in tailings dams are generally lower than those of standard earth dams. Previously, other authors have shown that embankment geometry and variation in permeability can be responsible for a concave upwards steady state seepage line.

Analytic Solution to a Problem of Seepage in a Chequer-Board Porous Massif [PDF]

, 1997
A study is made of steady two-dimensional seepage in a porous massif composed by a double-periodic system of 'white' and 'black' chequers of arbitrary conductivity.

A Subgrid-Scale Model for Turbulent Flow in Porous Media

, 2019
Given the analogy between the filtered equations of large eddy simulation and volume-averaged Navier–Stokes equations in porous media, a subgrid-scale model is presented to account for the residual stresses within the porous medium. The proposed model is

Migration trajectories and blocking effect of the fine particles in porous media based on particle flow simulation

AIP Advances
The particle flow code method based on the discrete element method was used to establish the seepage migration model of fine particles [fine particles (FPs), i.e., suspended particles] in a porous medium.

Microscopic origins of shape effects on migration and clogging of fines in porous media using coupled CFD-iDEM

Acta Geotechnica
The unstable mechanical behavior of soil particles during suffusion, including migration and clogging of fine particles in porous media, is prone to induce seepage catastrophes.

Discernible Orientation for Tortuosity During Oxidative Precipitation of Fe(II) in Porous Media: Laboratory Experiment and Micro-CT Imaging

Minerals
In the mixing zone, where submarine groundwater carrying ferrous iron [Fe(II)] meets seawater with dissolved oxygen (DO), the oxidative precipitation of Fe(II) occurs at the pore scale (nm~μm), and the resulting Fe precipitation significantly influences ...
