Foam Generation, Propagation and Stability in Porous Medium
Transport in Porous Media, 2019 There have been several foam field applications in recent years. Foam treatments targeting gas mobility control in injectors as well as gas blocking in production wells have been performed without causing operational problems.

A MODEL FOR POROUS-MEDIUM COMBUSTION
The Quarterly Journal of Mechanics and Applied Mathematics, 1989 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. The model represents conservation of mass and energy for both the gas and solid species, whilst

Evaporation versus imbibition in a porous medium
Journal of Colloid and Interface Science, 2020 Predicting and controlling the liquid dynamics in a porous medium is of large importance in numerous technological and industrial situations. We derive here a general analytical solution for the dynamics of a flat liquid front in a porous medium, considering the combined effects of capillary imbibition, gravity and evaporation.

Stability for systems of porous medium type
Journal of Mathematical Analysis and Applications, 2022 We establish stability properties of weak solutions for systems of porous medium type with respect to the exponent $m$. Thereby we treat stability for the local case as well as for Cauchy-Dirichlet problems. Both degenerate and singular cases are covered.

Lattice Boltzmann Model for Gas Flow through Tight Porous Media with Multiple Mechanisms
Entropy, 2019 In the development of tight gas reservoirs, gas flow through porous media usually takes place deep underground with multiple mechanisms, including gas slippage and stress sensitivity of permeability and porosity.

Anisotropic Mesh Adaptation for Finite Element Solution of Anisotropic Porous Medium Equation [PDF]
, 2017 Anisotropic Porous Medium Equation (APME) is developed as an extension of the Porous Medium Equation (PME) for anisotropic porous media. A special analytical solution is derived for APME for time-independent diffusion. Anisotropic mesh adaptation for linear finite element solution of APME is discussed and numerical results for two dimensional examples ...

Correlation effects during liquid infiltration into hydrophobic nanoporous mediums
, 2010 Correlation effects arising during liquid infiltration into hydrophobic porous medium are considered. On the basis of these effects a mechanism of energy absorption at filling porous medium by nonwetting liquid is suggested.
