Solute transport in porous media with equilibrium and non-equilibrium multiple-site adsorpition: Travelling weaves.

We study travelling wave solutions of a model describing solute transport through porous media, where the chemical species undergoes absorption, i.e. a retention/release reaction with the surface of the porous sceleton. Processes of this type are of fundamental importance in different fields. We do not consider the process at the microscopic scale of single grains and pores, but at the microscopic scale appropriate for the measurement of the phenomena described above
