Tornados and cyclones driven by Magneto-hydrodynamic forces

Abdellah Kharicha et al.

Summary: A numerical analysis is conducted to investigate the diverse flow structures generated in a conducting fluid due to the interaction of an electric current source with an external axial magnetic field. The results reveal various swirling flow patterns depending on the Shercliff and Hartmann numbers. The findings have implications for understanding flow structures in atmospheric phenomena, aluminum reduction cells, electro-metallurgical processes, and liquid metal batteries.

Efficient mixing by swirling electrovortex flows in liquid metal batteries

W. Herreman et al.

Summary: This study demonstrates that swirling electrovortex flows can significantly enhance the mixing of alloys in the bottom layer of liquid metal batteries during discharge. By identifying a novel scaling law for the intensity of these flows and using a model developed in a previous study, the minimal intensity of the external magnetic field required for this enhancement is estimated.
