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.

A framework for computing effective boundary conditions at the interface between free fluid and a porous medium [PDF]
Journal of Fluid Mechanics, 2016 Interfacial boundary conditions determined from empirical or ad hoc models remain the standard approach to model fluid flows over porous media, even in situations where the topology of the porous medium is known.

Dispersion of motile bacteria in a porous medium
Journal of Fluid Mechanics, 2022 Understanding flow and transport of bacteria in porous media is crucial to technologies such as bioremediation, biomineralization and enhanced oil recovery. While physicochemical bacteria filtration is well documented, recent studies showed that bacterial motility plays a key role in the transport process.

“Flow of Electrolytes in a Porous Medium” [PDF]
Journal of Applied Mechanics and Technical Physics, 2008 A two-scale model of ion transfer in a porous medium is obtained for one-dimensional horizontal flows under the action of a pressure gradient and an external electric field by the method of homogenization. Steady equations of electroosmotic flows in flat horizontal nano-sized slits separated by thin dielectric partitions are averaged over a small-scale

A General Fractional Porous Medium Equation [PDF]
Communications on Pure and Applied Mathematics, 2012 AbstractWe develop a theory of existence and uniqueness for the following porous medium equation with fractional diffusion: \input amssym $$\left\{ {\matrix{ {{{\partial u} \over {\partial t}} + \left( { ‐ \Delta } \right)^{\sigma /2} \left( {\left| u \right|^{m ‐ 1} u} \right) = 0,} \hfill & {x \in {\Bbb R} ^N ,\,\,t > 0,} \hfill \cr {u\

Pressure Wave Interaction with Fractured Porous Zone in Porous Medium
Учёные записки Казанского университета: Серия Физико-математические наукиThe propagation of a pressure wave in a porous medium with a fractured porous zone was numerically investigated. The study used a two-velocity model of a porous medium and a three-velocity model of a fractured porous medium. The problem was examined in a
