Electrohydrodynamic transport in compressible nanoporous packed beds

In nanoporous packed beds, fluid flow and charge transport are closely interrelated due to the formation of the electrochemical double layers on the solid-liquid interfaces. This study presents an empirical model for the hydraulic permeability of packed beds and a capillary model for the interaction of mass and charge transport. A numerical investigation confirms the empirical model for the hydraulic permeability and gives further insight into the structure of the packed beds.
