Numerical study of the process of unsteady flow in a three-layer porous medium

open access: yesMagazine of Civil Engineering, 2023
The unsteady fluid flow in a three-layer porous medium is numerically investigated and is an important and topical problem. An analytical solution of the equation for the pressure fluid layer is obtained on the basis of the theory of elastic regime ...

Equilibrium phase transitions in a porous medium [PDF]

open access: yesPhysical Review B, 1996
Static critical phenomena of a three-dimensional Ising model confined in a porous medium made by spinodal decomposition have been studied using large-scale Monte Carlo simulations. We thus examine the influence of the geometry of Vycor-like materials on phase transitions.

Analytical and numerical stability analysis of Soret-driven convection in a horizontal porous layer [PDF]

open access: yes, 2007
We present an analytical and numerical stability analysis of Soret-driven convection in a porous cavity saturated by a binary fluid. Both the mechanical equilibrium solution and the monocellular flow obtained for particular ranges of the physical ...

A MODEL FOR POROUS-MEDIUM COMBUSTION

open access: yesThe Quarterly Journal of Mechanics and Applied Mathematics, 1989
Summary: A model of time-dependent porous-medium combustion is presented. The model is of combustion in a three-dimensional porous medium. The typical situation envisaged is the combustion of a non-deforming porous solid medium through which a gas such as air passes.

A two-pressure model for slightly compressible single phase flow in bi-structured porous media [PDF]

open access: yes, 2012
Problems involving flow in porous media are ubiquitous in many natural and engineered systems. Mathematical modeling of such systems often relies on homogenization of pore-scale equations and macroscale continuum descriptions.

Three-dimensional spatially localized binary-fluid convection in a porous medium [PDF]

open access: yes, 2013
Three-dimensional convection in a binary mixture in a porous medium heated from below is studied. For negative separation ratios steady spatially localized convection patterns are expected.

Potential applications of distributed optical fiber sensor in hydrate‐induced sedimentary deformation research

open access: yesEnergy Science & Engineering, 2022
Natural gas hydrate is regarded as a potential clean energy source. However, hydrate phase transition during gas production leads to significant hydrate‐bearing sedimentary layer deformation, which is one of the main obstacles for safe hydrate ...
