Electro-vortex flow in a liquid metal battery electrode with annular current collector
A Ranjan, S Jindal - APS Division of Fluid Dynamics Meeting …, 2020 - ui.adsabs.harvard.edu
Electro-vortex flow (EVF) develops when electric current lines converge or diverge inside a
conducting fluid, when the curl of the Lorentz force is non-zero. In a three-layered liquid
metal battery (LMB), the EVF occurs near the current collectors and drives a flow away from
the wall. In a recent study on an Mg-Sb LMB with circular current collector, it was observed
that even in a moderate size LMB, the EVF could be strong enough to pinch the thin
electrolyte layer and cause short-circuit. In this study, we conduct numerical simulations of …
