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

A Monte Carlo algorithm, which incorporates tensile effects as well as diff usion, is proposed. It provides a description of water transport in a dryin g porous gel close to saturation permitting an interpretation of magnetic r esonance imaging profiles. Boltzmann's transformation of the one-dimensiona l diffusion equation is employed to examine the onset of a non-Fickian tran sport regime caused by the collective motion of diffusers associated with t ensile forces.
