Effect of micropores on the effective diffusion coefficient

Kinetics and Catalysis, 2016
The effective diffusion coefficient for catalysts differing in their porous structure has been derived from experimental data on H2S conversion in the Claus reaction. The effective diffusion coefficient increases under conditions of catalyst deactivation due to sulfur condensation in micropores.

Effective Diffusion Coefficient

Defect and Diffusion Forum, 2018
The diffusion of a B element into an A matrix was studied by the random walk theory. Considering that concentration of B element in the A matrix is very low, the jumps of diffusing atoms are independent of each other. The A matrix is a two-region material with different properties, such as a two-phase material, a single crystal with dislocations, or ...

Effective diffusion coefficient in 2D periodic channels

The Journal of Chemical Physics, 2014
Calculation of the effective diffusion coefficient D(x), depending on the longitudinal coordinate x in 2D channels with periodically corrugated walls, is revisited. Instead of scaling the transverse lengths and applying the standard homogenization techniques, we propose an algorithm based on formulation of the problem in the complex plane.

Note: Effective diffusion coefficient in heterogeneous media

The Journal of Chemical Physics, 2012
A closed formula for the effective diffusion coefficient in a heterogeneous medium with periodically distributed inclusions is derived using the extended effective medium theory. It is shown that the expression for the effective diffusion coefficient is an exact result, since it is identical to the expression obtained using the Lifson-Jackson formula.

Effective Diffusion Coefficient in Porous Media

Journal of Applied Physics, 1963
Recent calculations by Prager of upper bounds for the effective diffusion coefficient (or conductivity) in porous media, in terms of certain statistical parameters of the random geometry, are reformulated so as to apply specifically to a bed of spherical particles.
