Pushing Droplet Through a Porous Medium. [PDF]

open access: yesTransp Porous Media, 2022
AbstractI use a mechanical model of a soft body to study the dynamics of an individual fluid droplet in a random, non-wettable porous medium. The model of droplet relies on the spring–mass system with pressure. I run hundreds of independent simulations. I average droplets trajectories and calculate the averaged tortuosity of the porous domain.

System of porous medium equations [PDF]

open access: yesJournal 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]

open access: yesНанотехнологии 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.

Effects of porous medium filling on thermally developing forced convection in a parallel plate channel

open access: yesInternational Journal of Thermofluids, 2023
This study obtains the semi-analytical solutions and explores the thermal characteristics of a thermally developing flow in a parallel plate channel, partially filled with a porous medium at the core, while considering local thermal non-equilibrium ...

Analysis of Longitudinal Guided Wave Propagation in a Liquid-Filled Pipe Embedded in Porous Medium

open access: yesApplied 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

open access: yesNanomaterials, 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.
