The academic and industrial applications of electrohydrodynamic transport in nanoporous packed beds range from micro- and nanofluidics to chemical engineering processes: Electroosmotic micropumps can be used to drive liquids in micro-fluidic systems without requiring any moving parts. Consequently, they are inexpensive and robust and can be manufactured in small dimensions. Electrowashing is a new and promising purification process, where contaminants are extracted from dead-end pores within the particles by an electric field and subsequently sheared-off by a pressure-driven permeation.The aim of this study is to further understand how physicochemical and structural parameters affect the fluid flow and charge transport in nanoporous packed beds, based on a combined experimental and numerical approach.
