Electro-Vortex flow in Liquid Metal Batteries

Résumé

We use our multiphase MHD solver SFEMaNS [1-3] to study the generation of flows in (cylindrical) liquid metal batteries due to the Electro-Vortex-Flow (EVF) phenomenon, i.e. the interaction of a non-uniform current with the magnetic field that it generates. First, we discuss the typical intensity and structure of the axisymmetric flow in a liquid metal column covered by many previous studies. After that, we focus on EVF in liquid metal batteries. We discuss the deformation of the electrolyte-liquid metal interfaces caused by EVF and we characterize how EVF helps in mixing the bottom alloy layer. [1] J.-L. Guermond, J. Léorat, F. Luddens, C.
