Abstract

In this paper a Monte Carlo method is introduced for determining the diffusivity in the void space of porous media constructed from spheres. We studied ordered and random arrangements of spheres, the latter with different sizes. It is found that the effect of structure on the diffusivity is fairly slight. The empirical curve of Neale and Nader is shown to provide a convenient upper bound. The result of Bruggemann provides a convenient lower bound.
