A note on withdrawal from a two-layer fluid through a line sink in a porous medium [PDF]
, 2008 The steady response of the free surface of a fluid in a porous medium is considered during extraction of the fluid through a line sink. A conformal-mapping approach is used to derive exact solutions to a family of problems in which the line sink is ...

Quenching for Porous Medium Equations
Tamkang Journal of Mathematics, 2021 This paper studies the following two porous medium equations with singular boundary conditions. First, we obtain that finite time quenching on the boundary, as well as kt blows up at the same finite time and lower bound estimates of the quenching time of the equation kt = (kn)xx + (1 − k)−α, (x,t) ∈ (0,L) × (0,T) with (kn)x (0,t) = 0, (kn)x (L,t) = (1 −

Mechanisms of dispersion in a porous medium [PDF]
Journal of Fluid Mechanics, 2018 This paper studies the mechanisms of dispersion in the laminar flow through the pore space of a three-dimensional porous medium. We focus on preasymptotic transport prior to the asymptotic hydrodynamic dispersion regime, in which solute motion may be described by the average flow velocity and a hydrodynamic dispersion coefficient.

Numerical study of the process of unsteady flow in a three-layer porous medium
Magazine 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]
Physical 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.

Fluid drainage from the edge of a porous reservoir [PDF]
, 2013 We report theoretical and experimental studies to describe buoyancy-driven fluid drainage from a porous medium for configurations where the fluid drains from an edge. We first study homogeneous porous systems.

Characterization of Catalytic Porous Medium Using Platinum for Micro-combustion Application
MATEC Web of Conferences, 2014 In this study, catalytic alumina porous medium has been fabricated by using platinum as an active material for micro-combustion application. Platinum has been deposited onto porous medium surface via wet impregnation method.

Coning during withdrawal from two fluids of different density in a porous medium [PDF]
, 2009 The steady response of the interface between two fluids with different density in a porous medium is considered during extraction through a line sink. Supercritical withdrawal, or coning as it is often called, in which both fluids are being withdrawn, is
