Nonaxisymmetric instabilities in turbulent electromagnetic pumps

By Paola Rodriguez Imazio and Christophe Gissinger
The stability of annular electromagnetic pumps (EMPs) is investigated through 3D direct numerical simulations. When induction effects dominate dissipative processes, linear induction EMPs become unstable and lead to non-axisymmetric states relatively different from what was predicted by previous theoretical models. We show that the 3D destabilization of the flow is... Show more
