Influence of electromagnetic boundary conditions onto the onset of dynamo action in laboratory experiments

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/229538We study the onset of dynamo action of the Riga and Karlsruhe experiments with the addition of an external wall, the electro-magnetic properties of which being different from those of the fluid in motion. We consider a wall of different thickness, conductivity and permeability. We also consider the case of a ferro-fluid in motion.9 pages, 9 figuresFluid DynamicsGeophysicsInfluence of electromagnetic boundary conditions onto the onset of dynamo action in laboratory experimentstext
