Cross-property connections between Young's modulus and diffusion coefficient of two-phase composite
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2021 The paper interrelates changes in the effective elastic and diffusion properties of a two-phase composite caused by inhomogeneities. The correlation is based on similarities between the microstructural parameters in whose terms the effective properties ...

Characterization of Effective Diffusion within Viscoelastic Fluids with Elastic Instabilities
Fluids, 2022 We considered effective diffusion, characterized by magnitudes of effective diffusion coefficients, in order to quantify mass transport due to the onset and development of elastic instabilities.

Scale Dependency of the Effective Matrix Diffusion Coefficient [PDF]
Vadose Zone Journal, 2004 It has been recognized that matrix diffusion is an important process for retarding solute transport in fractured rock. Based on analyses of tracer transport data from a number of field tests, we demonstrate for the first time that the effective matrix‐diffusion coefficient may be scale dependent and generally increases with test scale.

Effects of diffusive property heterogeneity on effective matrix diffusion coefficient for fractured rock [PDF]
Water Resources Research, 2006 Heterogeneities of diffusion properties are likely to influence the effective matrix diffusion coefficient determined from tracer breakthrough curves. The objectives of this study are (1) to examine if it is appropriate to use a single, effective matrix diffusion coefficient to predict breakthrough curves in a fractured formation, (2) to examine if a ...

Corrections to Einstein's relation for Brownian motion in a tilted periodic potential [PDF]
, 2012 In this paper we revisit the problem of Brownian motion in a tilted periodic potential. We use homogenization theory to derive general formulas for the effective velocity and the effective diffusion tensor that are valid for arbitrary tilts. Furthermore,
