چکیده
Based on the capillary hypothesis and fractal theory, a mathematical model for calculating effective gas diffusion coefficient in porous media is established. By using geometry pore area dimension, tortuosity dimension connectivity are introduced to quantitatively characterize real internal structure media. An derived, influence of multi-scale microstructure parameters discussed. The results show that approximates linearly increase with porosity, positive correlation, but negatively related it. In case different porosities, varies change diameter ratio, increases connectivity.

Probing porous media with gas diffusion NMR.
We show that gas diffusion nuclear magnetic resonance (GD-NMR) provides a powerful technique for probing the structure of porous media. In random packs of glass beads, using both laser-polarized and thermally polarized xenon gas, we find that GD-NMR can accurately measure the pore space surface-area-to-volume ratio, S/V rho, and the tortuosity, alpha (the latter quantity being directly related ...

This work is concerned with conditional averaging methods which can be used for modeling of transport in porous media with volume reactions in the fluid phase and surface reactions at the fluid/solid interface. The model under consideration takes into account convection, diffusion within the pores and on larger scales, and homogeneous and heterogeneous reactions. Near the interface with fractal...

متن کاملCalculation of the Effective Diffusion Coefficient for Heterogeneous Media
1 Introduction In this paper we discuss the range of the applicability of our recent approach [1] for the effective diffusion coefficient (mobility) in two-phase systems, e.g. composite materials, porous media, polymer blends, matrices with inclusions. We derived the equation for D eff as a function of the partial diffusion coefficients of a defect (or probe particle) in inclusions, D 1 , with ...
