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. We propose a non-empirical and accurate method to compute the effective boundary conditions at the interface between a porous surface and an ...

Pressures Inside a Nano-Porous Medium. The Case of a Single Phase Fluid [PDF]
Frontiers in Physics, 2019 We define the pressure of a porous medium in terms of the grand potential and compute its value in a nano-confined or nano-porous medium, meaning a medium where thermodynamic equations need be adjusted for smallness.

Homogenization of Bingham Flow in thin porous media [PDF]
arXiv, 2019 By using dimension reduction and homogenization techniques, we study the steady flow of an incompresible viscoplastic Bingham fluid in a thin porous medium. A main feature of our study is the dependence of the yield stress of the Bingham fluid on the small parameters describing the geometry of the thin porous medium under consideration. Three different

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.

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.
