The Effective Diffusion Coefficient for Porous Rubble
, 1990 Each waste package in the proposed Yucca Mountain repository is to be separated from surrounded unsaturated rock by a 2-cm air gap annulus. However, if the annulus becomes filled with rock and rubble, there can exist pathways for diffusive release of radionuclides through pore liquid, even if the repository remains unsaturated.

POTENTIAL SCALE DEPENDENCE OF EFFECTIVE MATRIX DIFFUSION COEFFICIENT [PDF]
, 2006 It is well known that matrix diffusion (mass transfer between fractures and the rock matrix through molecular diffusion) can significantly retard solute transport processes in fractured rock, and therefore is important for analyzing a variety of problems, including geological disposal of nuclear waste.

Mathematical Model for Effective Gas Diffusion Coefficient in Multi-scale Fractal Porous Media [PDF]
E3S Web of Conferences, 2021 Based on the capillary hypothesis and fractal theory, a mathematical model for calculating the effective gas diffusion coefficient in porous media is established. By using fractal geometry theory, pore area fractal dimension, tortuosity fractal dimension

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 ...
