Abstract We study the effect of magnetic field on the electro-hydrodynamics of ion transport in a liquid electrolyte
near an ion-selective membrane using direct numerical simulation. Ion transport across the ion selective
membrane plays an essential role in many electro-hydrodynamic and electro-microfluidic systems. Above a
critical voltage, electroconvective instability occurs near the membrane surface, causing vortical flows in
liquid electrolyte which enhances the mixing of cations and anions, increases the ion transport efficiency
and causes current fluctuations. When the system is under a magnetic field, the Lorentz force generated by
the ion movement can significantly change the flow of electrolyte solution.… More >
