Properties of a Composite Material with Mixed Imperfect Contact Conditions
We present an analytical solution of a mixed boundary value problem for an unbounded 2D doubly periodic domain which is a model of a composite material with mixed imperfect interface conditions.

In situ mixing of organic matter decreases hydraulic conductivity of denitrification walls in sand aquifers [PDF]
In a previous study, a denitrification wall was constructed in a sand aquifer using sawdust as the carbon substrate. Ground water bypassed around this sawdust wall due to reduced hydraulic conductivity.

On the reaction rate distribution in porous electrodes
Reaction rate distribution across porous electrodes in Li-ion battery applications largely determines the overall battery performance. In the present work, expressions for the reaction rate distribution across porous electrodes are analytically derived ...

Effect of solid thermal conductivity and particle-particle contact on effective thermodiffusion coefficient in porous media [PDF]
Transient mass transfer associated to a thermal gradient through a saturated porous medium is studied experimentally and theoretically to determine the effect of solid thermal conductivity and particle-particle contact on thermodiffusion processes.

A further discussion on the effective thermal conductivity of metal foam: An improved model [PDF]
In this study, we explain the causes and effects of the geometrical impossible result encountered in the widely adopted tetrakaidecahedron model (Boomsma and Poulikakos, 2001; Dai et al., 2010) for the effective thermal conductivities (ETCs) of metal ...

Effective Conductivity of an Isotropic Heterogeneous Medium of Lognormal Conductivity Distribution [PDF]
The study aims at deriving the effective conductivity K ef of a three-dimensional heterogeneous medium whose local conductivity K(x) is a stationary and isotropic random space function of lognormal distribution and finite integral scale I Y . We adopt a

Broadening the Bandwidth of Epsilon-Near-Zero Metamaterials with Embedded Square Frames
A narrow frequency bandwidth of epsilon-near-zero metamaterials limits the use of many optical, microwave, and electronic devices. In this paper, we propose a recipe to broaden the operational bandwidth by employing a structure of properly tailored ...
