Mass transport subject to time-dependent flow with nonuniform sorption in porous media
Mass transport subject to time-dependent flow with nonuniform sorption in porous media
We address the description of solutes flow with trapping processes in porous media. Starting from a small-scale model for tracer particle trajectories, we derive the corresponding governing equations for the concentration of the mobile and immobile phases within a fractal mobile-immobile model approach. We show that this formulation is fairly …
