A physical model of convective-dispersive transport in an intergranular porous material

A physical model for tracer transport in an intergranular porous material is presented. Particularly, the measured temporal variations of a tracer mass concentration inside the physical model are compared to the one predicted for the same boundary and initial conditions by the 1D and 2D analytical solutions of the governing differential equation. A non-reactive tracer and steady flow conditions are considered. The Péclet number for the considered flow is such that the molecular diffusion can be neglected.
