Water Resources Research, 2023 Fines migration driven by fluid flows often causes pore clogging in porous media and thus reduces the permeability of the porous media. The clogging can pose serious problems in various practices, such as formation damage in hydrocarbon reservoirs ...

DEM modelling of unsaturated seepage flows through porous media
Computational Particle Mechanics, 2021 A new hybrid discrete–continuum numerical approach that explores the key advantages of both discrete and continuum approaches is proposed to model unsaturated seepage flows through porous media. In contrast to existing approaches where a porous medium is

A Study of the Non-Linear Seepage Problem in Porous Media via the Homotopy Analysis Method
Energies, 2023 A non-Darcy flow with moving boundary conditions in a low-permeability reservoir was solved using the homotopy analysis method (HAM), which was converted into a fixed-boundary mathematical model via similarity transformation.

A Dimension-Reduced Line-Element Method to Model Unsaturated Seepage Flow in Porous Media
Water, 2023 Contrary to the continuum hypothesis, which averages water flow across the entire domain, including both grains and pores, the line-element model concentrates unsaturated flow in the pore space in the intermediate region of horizontal and vertical ...

Lagrange’s equations for seepage flow in porous media with a mixed Lagrangian-Eulerian description
Acta Mechanica Sinica, 2023 传统数值模型大多使用偏微分方程来描述渗流问题, 并使用加权余量和有限差分技术来求解该方程. 这类方程建立在空间点的角度之上, 在数学上源于无穷小的概念. 本文发展了一种求解渗流问题的能量方法, 将拉格朗日方程应用于渗流系统的描述, 而非直接采用偏微分方程进行描述. 通过对代表性体积单元的能量进行积分而建立拉格朗日泛函, 并采用合理的广义坐标对该泛函进行变分得到系统控制方程. 将所得到的积分方程, 由拉格朗日描述转化为欧拉描述, 以此提高计算精度.

Environmental science and pollution research international, 2023 Particle bridging owing to the confinement of the pore structure affects the transport and retention of particles in porous media. Particle motion driven by gravities were well investigated, whose filtration is mainly affected by the ratio of the ...

Spherical seepage model of Bingham fluid in rough and low-permeability porous media
Fluid Dynamics Research, 2023 Based on the microstructure of porous media that exhibits statistical self-similarity fractal features, this paper investigates the radial flow characteristics of non-Newtonian fluids within rough porous media. The analytical equation of permeability and

Porous Media Model of Reservoir considering Seepage Stress Coupling and Seepage Field Analysis
Geofluids, 2023 In the process of reservoir exploitation, the range of rock stress field changes is much larger than the reservoir area where the seepage occurs; so the amount of calculation of the existing seepage stress full coupling method is often very huge.
