Fundamental theoretical study of nanoscale ion transport through charged porous rocks: Part II-diffusion-advection

Depending on the rock permeability, different mass transport mechanisms have to be distinguished. Whereas mass transport through porous rocks characterized by low permeabilities is governed by diffusion, mass transport through highly permeable rocks is governed by advection. Coupled diffusive-advective mass transport then plays an important roll in many geoengineering systems, such as mineralization, ore body genesis and pollutant migration (including the transport of bacteria, viruses and other microorganisms). ..
