Tortuosity-porosity relation in porous media flow [PDF]
Physical Review E, 2008 We study numerically the tortuosity--porosity relation in a microscopic model of a porous medium arranged as a collectin of freely overlapping squares. It is demonstrated that the finite-size effects and the discretization errors, which were ignored in previous studies, may cause significant underestimation of tortuosity.

Chaotic Advection at the Pore Scale: Mechanisms, Upscaling and Implications for Macroscopic Transport [PDF]
, 2016 The macroscopic spreading and mixing of solute plumes in saturated porous media is ultimately controlled by processes operating at the pore scale. Whilst the conventional picture of pore-scale mechanical dispersion and molecular diffusion leading to ...

Velocity measurements of a dilute particulate suspension over and through a porous medium model
, 2020 We experimentally examine pressure-driven flows of 1%, 3%, and 5% dilute suspensions over and through a porous media model. The flow of non-colloidal, non-Brownian suspensions of rigid and spherical particles suspended in a Newtonian fluid is considered ...

Multiscale simulations of porous media flows in flow-based coordinate system [PDF]
, 2008 In this paper, we propose a multiscale technique for the simulation of porous media flows in a flow-based coordinate system. A flow-based coordinate system allows us to simplify the scale interaction and derive the upscaled equations for purely ...

Research on carbonate reservoir interwell connectivity based on a modified diffusivity filter model
Open Physics, 2017 According to the solution of dual-porosity model, a diffusivity filter model of carbonate reservoir was established, which can effectively illustrate the injection signal attenuation and lag characteristic.

Energy Reports, 2022 The Vereiskiy reservoir (Perm Region, Russia) is one of the complicated oil-bearing carbonate formations. It consists of interbedded carbonates and clayey rocks with low interbedded thickness (3–6 m), which makes its development unprofitable.

Energies, 2023 In this study, we present a novel comparison between pore-structure (PS) and representative elementary volume (REV) methods for modelling fluid flow through porous media using a second-order lattice Boltzmann method (LBM).
