Controlled ion transport in the subsurface
A coupled advection–diffusion–electromigration system
Ion transport within saturated porous media is an intricate process in which efficient ion delivery is desired in many engineering problems. However, controlling the behavior of ion transport proves challenging, as ion transport is influenced by a variety of driving mechanisms, w

A Pore-Scale Model for Electrokinetic In situ Recovery of Copper
The Influence of Mineral Occurrence, Zeta Potential, and Electric Potential
Abstract: Electrokinetic in-situ recovery is an alternative to conventional mining, relying on the application of an electric potential to enhance the subsurface flow of ions. Understanding the pore-scale flow and ion transport under electric potential is essential for petrophysi
