Natural convection and the evolution of a reactive porous medium [PDF]
, 2011 We describe a mathematical model of buoyancy-driven flow and solute transport in a saturated porous medium, the porosity and permeability of which evolve through precipitation and dissolution as a mineral is lost or gained from the pore fluid. Imposing a

Nanogel formation of polymer solutions flowing through porous media [PDF]
, 2012 A gelation process was seen to occur when Boger fluids made from aqueous solutions of polyacrylamide (PAA) and NaCl flowed through porous media with certain characteristics.

System of porous medium equations [PDF]
Journal of Differential Equations, 2021 We investigate the evolution of population density vector, $\bold{u}=\left(u^1,\cdots,u^k\right)$, of $k$-species whose diffusion is controlled by its absolute value $\left|\bold{u}\right|$. More precisely we study the properties and asymptotic large time behaviour of solution $\bold{u}=\left(u^1,\cdots,u^k\right)$ of degenerate parabolic system \begin{

Mathematical modeling of physical and chemical processes in porous media in solving the problems of nanocomposite materials and water-filling [PDF]
Нанотехнологии в строительстве, 2023 : Introduction. The complexity and laboriousness of system studies of physical and chemical processes in the volume and at the interface of the porous medium determines the need to apply mathematical modeling.

Dynamics of osmosis in a porous medium [PDF]
Royal Society Open Science, 2014 We derive from kinetic theory, fluid mechanics and thermodynamics the minimal continuum-level equations governing the flow of a binary, non-electrolytic mixture in an isotropic porous medium with osmotic effects. For dilute mixtures, these equations are linear and in this limit provide a theoretical basis for the widely used semi-empirical

, 2022 A porous medium can be defined as a material which contains spaces which, when continuous in some way, enable the movement of fluids, air and materials of different chemical and physical properties. The ability of a porous medium to permit the movement of fluids, air or a mixture of different fluids is related to porosity and the variability of pore ...

Analysis of Longitudinal Guided Wave Propagation in a Liquid-Filled Pipe Embedded in Porous Medium
Applied Sciences, 2021 To study the leakage situation of a liquid-filled pipe in long-term service, a model of a liquid-filled pipe embedded in an infinite porous medium as well as in a finite porous medium is designed.

The Thermal Performance Analysis of an Al2O3-Water Nanofluid Flow in a Composite Microchannel
Nanomaterials, 2022 Partial filling of porous medium insert in a channel alleviates the tremendous pressure drop associated with a porous medium saturated channel, and enhances heat transfer at an optimum fraction of porous medium filling.
