Scale Dependency of the Effective Matrix Diffusion Coefficient
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 that the effective matrix-diffusion coefficient may be scaledependent and generally increases with test scale. A preliminary theoretical explanation of this scale dependency is also presente...
متن کاملPreconditioned Generalized Minimal Residual Method for Solving Fractional Advection-Diffusion Equation
Introduction Fractional differential equations (FDEs) have attracted much attention and have been widely used in the fields of finance, physics, image processing, and biology, etc. It is not always possible to find an analytical solution for such equations. The approximate solution or numerical scheme may be a good approach, particularly, the schemes in numerical linear algebra for solving ...
متن کاملBrownian motion through a two-dimensional glass: Trapping, hopping, and diffusion
Computer simulations and computational diagnostics are used to study a Monte Carlo Brownian walker moving through a glass of immobile force centers. Clear evidence for distinct trapping, hopping, and hindered-diffusive regimes is seen in the mean-square displacement and the probability distribution P(r ,t) for a step r during delay t . In the hopping regime distinct time scales for intratrap an...
متن کاملThe Open-Access Journal for the Basic Principles of Diffusion Theory, Experiment and Application Hexane Self-Diffusion in Bed of Glass Spheres. Testing Applicability Range of the Pore-Hopping Model
1. Introduction PFG NMR experiment is in principle capable to provide important transport-structural parameters of system consisting of a liquid confined in a porous matrix such as surface-to-volume ratio and tortuosity. The apparent diffusion coefficient is easily obtained in the case of Gaussian shape of the diffusion propagator. Dependence of these values on the diffusion time in a short tim...
متن کاملA New Resistance Model for Interpretation of Gas Permeation Data of Composite and Asymmetric Membranes
In this work a new resistance model has been presented based on that of Henis-Tripodi which can be used for interpretation of gas permeation data in composite and asymmetric membranes. In contrast to the previous works, in this model the fraction of the support layer surface that includes the pores filled with coating material has been taken into account. The influences of the filled pores on s...
