Acoustical properties of double porosity granular materials [PDF]
The Journal of the Acoustical Society of America, 2011 Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating properties. An emerging field is the study of the acoustical properties of multiscale porous materials.

Sedimentation-consolidation of a double porosity material [PDF]
Computers and Geotechnics, 2007 This paper studies the sedimentation-consolidation of a double porosity material, such as lumpy clay. Large displacements and finite strains are accounted for in a multidimensional setting.

Fluid Discrimination in Ultra-Deep Reservoirs Based on a Double Double-Porosity Theory
Frontiers in Earth Science, 2021 We develop a methodology, based on rock-physics templates, to effectively identify reservoir fluids in ultra-deep reservoirs, where the poroelasticity model is based on the double double-porosity theory.

Influence of nonlocal on a rotating thermoelastic medium with diffusion and double porosity [PDF]
Scientific ReportsIn this paper, we have studied the thermodynamical interactions in a two-dimensional thermoelastic diffusion in homogeneous isotropic medium with nonlocal, rotation and double porosity in the context of Green–Lindsay theory. A thermal load was applied to

Discrete double-porosity models for spin systems [PDF]
Mathematics and Mechanics of Complex Systems, 2015 We consider spin systems between a finite number $N$ of "species" or "phases" partitioning a cubic lattice $\mathbb{Z}^d$. We suppose that interactions between points of the same phase are coercive, while between point of different phases (or, possibly ...

Non-simple elastic materials with double porosity structure
Archives of Mechanics, 2022 This paper is concerned with a strain gradient theory of elastic materials that have a double porosity structure. Firstly, we present the basic equations and the boundary conditions of the nonlinear theory.

Microstructure and Pore Characteristics of a SUS316L Gas Filter Fabricated by Wet Powder Spraying [PDF]
Archives of Metallurgy and Materials, 2022 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 ...

Human hepatic cell behavior on polysulfone membrane with double porosity level [PDF]
, 2013 In the membrane-based bioartificial livers developed up to now,the hepatic cells were located either in the fibers lumen or in the cartridge,with limited capacity for cell hosting.Here,we designed a polysulfone (PSU) membrane with a double porosity ...
