Understanding and Controlling Metal Pad Roll Instability in High-Capacity Liquid Metal Battery Systems
Abstract: The present study delves into the roll instability of metal pads within cylindrical liquid metal battery cells, focusing on the characteristics, control, and modeling of the instability within an energetic materials context. Explicit formulas are derived that offer theoretical benchmarks for magnetohydrodynamic solvers OpenFOAM and SFEMaNS, revealing an excellent alignment with experimental observations on gravity wave damping rates in multilayered liquid metal battery systems. Instability thresholds are analyzed for metal …
