Monte Carlo simulations of non-Fickian water transport in a saturated porous gel.

A Monte Carlo algorithm, which incorporates tensile effects as well as diffusion, is proposed. It provides a description of water transport in a drying porous gel close to saturation permitting an interpretation of magnetic resonance imaging profiles. Boltzmann's transformation of the one-dimensional diffusion equation is employed to examine the onset of a non-Fickian transport regime caused by the collective motion of diffusers associated with tensile forces.
