On the hydrodynamics and heat convection of an impinging external flow upon a cylinder with transpiration and embedded in a porous medium [PDF]

open access: yes, 2017
This paper extends the existing studies of heat convection by an external flow impinging upon a flat porous insert to that on a circular cylinder inside a porous medium.

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 ...

Clogging a Porous Medium

open access: yes, 2021
Flows through porous media can carry suspended and dissolved materials. These sediments may deposit inside the pore-space and alter its geometry. In turn, the changing pore structure modifies the preferential flow paths, resulting in a strong coupling between structural modifications and transport characteristics.

A General Fractional Porous Medium Equation [PDF]

open access: yesCommunications 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\

Characterization of Catalytic Porous Medium Using Platinum for Micro-combustion Application

open access: yesMATEC 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.

Flow through a porous medium

open access: yesMechanics Research Communications, 1987
Recently the first author [ibid. 11, 277-279 (1984; Zbl 0548.76072)] has studied the flow through a very porous medium bounded by semi-infinite plate when the free-stream velocity is constant. The purpose of this paper is the study of the steady flow through a very porous medium bounded by a semi-infinite plate when the fluid is viscous and the free ...

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 ...

Effect of Anionic Surfactants on the Oil–Water–Rock Interactions by an Improved Washburn Method

open access: yesMolecules
The complex and variable structure of subsurface oil reservoirs as well as the small pore throat size of reservoirs make it extremely important to investigate the effect of oil–water–rock interactions for enhancing oil recovery. In this paper, the powder
