Abstract
To study the properties of the flow of a marker through an irregular packed bed, porosity is described by stochastic processes with exponentially deca ying correlation functions. We show that the ensemble average concentration of the marker satisfies a fractional diffusion equation. (C) 2001 American Institute of Physics.
