Microstructure and Pore Characteristics of a SUS316L Gas Filter Fabricated by Wet Powder Spraying [PDF]
In this study, a flake-shaped metal powder was coated on a tube shaped pre-sintered 316L stainless steel support using a wet powder spraying process to fabricate a double pore structure, and the pore characteristics were analyzed according to coating ...

Nonlinear “double porosity” type model
We consider a variational problem inf u∈H 1 (Ω) ∫ Ω {a ϵ |∇u ϵ | m +g|u ϵ | m - mf ϵ u ϵ }dx in a bounded domain Ω=ℱ (ϵ) ∪ℳ ¯ (ϵ) with a microstructure ℱ (ϵ) which is not in general periodic; aε=aε(x) is of order 1 in ℱ (ϵ) and sup x∈ℳ (ϵ) a ϵ (x)→0 as ε→0. A homogenized model is constructed.

Some remarks on single- and double-porosity modeling of coupled chemo-hydro-mechanical processes in clays [PDF]
Active clays are known to possess an aggregated structure, which justifies the use of double-porosity models to reproduce their behavior. Simulation of chemo-mechanical processes requires instead the introduction of a relevant number of coupled ...

SPH Simulation of Interior and Exterior Flow Field Characteristics of Porous Media [PDF]
At the present time, one of the most relevant challenges in marine and ocean engineering and practice is the development of a mathematical modeling that can accurately replicate the interaction of water waves with porous coastal structures. Over the last

Mathematical Problems in the Theory of Bone Poroelasticity
This paper concerns with the quasi-static theory of bone poroelasticity for materials with double porosity. The system of equations of this theory based on the equilibrium equations, conservation of fluid mass, the effective stress concept and Darcy’s ...

Modelling a hydration and heating column test on unsaturated bentonite using a double-porosity approach [PDF]
A controlled re-saturation of a heated 50 cm long column made of MX-80 bentonite pellets in the CIEMAT laboratory facilities (Madrid, Spain) has been running for 10 years (2011-2021).

Macroscopic modeling of double-porosity reservoirs [PDF]
Abstract This paper deals with the seepage of a fluid through a fractured porous medium. It summarizes important results obtained using the homogenization method for periodic structures. Thereby, unlike the phenomenological approaches, the macroscopic behaviors are deduced from the physics at the microscopic scales, without any prerequisite.
