A water retention model for compacted clays subjected to salinization and desalinization processes [PDF]

open access: yesE3S Web of Conferences, 2020
Environmental actions are known to induce relevant effects on the fabric of compacted active clays, which are successfully described by adopting a double porosity framework.

Modelling of Supercapacitors: Factors Influencing Performance [PDF]

open access: yes, 2016
The utilizable capacitance of Electrochemical Double Layer Capacitors (EDLCs) is a function of the frequency at which they are operated and this is strongly dependent on the construction and physical parameters of the device.

Study on Permeability and Blocking Resistance of Composite Specimen with Double-Layer Permeable Asphalt Mixture

open access: yesAdvances in Civil Engineering, 2019
In order to study the permeability and antiblocking performance of composite specimens with double-layer permeable asphalt mixture, three types of PAC-10 asphalt mixture with different target porosity (20%, 22%, and 24%) and PAC-16 asphalt mixture with a

Dual‐Scale Spiral Material for Balancing High Load Bearing and Sound Absorption

open access: yesAdvanced Science
Porous materials with sound absorption and load‐bearing capabilities are in demand in engineering fields like aviation and rail transportation. However, achieving both properties simultaneously is challenging due to the trade‐off between interconnected ...

Reflection and refraction of plane waves at the boundary of an elastic solid and double-porosity dual-permeability materials

open access: yesPetroleum Science, 2019
Phenomena of reflection and refraction of plane harmonic waves at a plane interface between an elastic solid and double-porosity dual-permeability material are investigated.

On-sample water content measurement for a complete local monitoring in triaxial testing of unsaturated soils [PDF]

open access: yes, 2012
To provide a complete local monitoring of the state of an unsaturated soil sample during triaxial testing, a local water content measurement device was adapted to a triaxial device comprising the measurement of local displacements (Hall effect ...

COUPLED ANALYSIS OF DOUBLE POROSITY SWELLING CLAYS

open access: yes, 2011
The understanding of the coupled behaviour of highly active swelling clays is better achieved considering two structural levels and their interactions in the context of a double-porosity model. Hydraulic equilibrium between the two porosity levels is not assumed.

Homogenized model for flow in partially fractured media

open access: yesElectronic Journal of Differential Equations, 2009
We derive rigorously a homogenized model for the displacement of one compressible miscible fluid by another in a partially fractured porous reservoir. We denote by $epsilon$ the characteristic size of the heterogeneity in the medium.
