Note: Effective diffusion coefficient in heterogeneous media
Juris Roberts Kalnin, Eugene A. Kotomin · 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.
