Electromgnetically Induced Flow Around a Cylinder


Electromgnetically Induced Flow Around a Cylinder

Thess, A.; Gerbeth, G.; Marty, P.

The unidirectional flow of an electrically conducting fluid around a cylinder of arbitrary electrical conductivity, which is driven by the interaction of a homogeneous electric current with a homogeneous magnetic field and the resulting force on the cylinder are calculated numerically without any approximation in a large range of parameters. Asymptotic solutions are derived for the case of very strong and very weak magnetic fields respectively. A comparison with experimental results on insulating and highly conducting cylinders leads to a partial agreement although inertial forces are not taken into account in the model. Finally, confinement effects are considered leading to a better agreement between theory and experiment.
