A wide range of applications, including electrochemical energy conversion, deionization,
and lab-on-a-chip devices involve transport phenomena in porous media or networks of
microchannels. Transport in such systems is governed by electrokinetic phenomena
describing the coupling between fluid flow, ion transport, and electrostatic effects. In these
systems, surface conduction through electric double layers (EDLs) can lead to nonlinear
dynamics such as deionization shocks. Additionally, when pore size varies randomly in …
