| Abstract Scope |
Liquid metal batteries are a promising energy storage technology where the electrodes and electrolyte are liquid. Understanding magnetically and thermally induced flows in these devices is crucial: although induced flows can enhance mass transfer, turbulent motions could disrupt the electrolyte layer and short the battery internally. Therefore, it is important to determine the current at which the transition to turbulent motion occurs.
We present results from a laboratory model developed for studying combined thermal convection and electrovortex flow in these batteries. Electrovortex flow occurs when a current interacts with its induced magnetic field in a conducting fluid, creating forces. Our experimental setup is a cylindrical container with an electrode entering the vessel at the top center. We characterize the different flows that are present as the current is varied (characteristic of battery transients). Our results can determine the operating current ranges at which liquid metal batteries are most stable. |
