Stability of the flow between two hemispherical electrodes


Stability of the flow between two hemispherical electrodes

Shatrov, V.; Gerbeth, G.

The stability of the steady laminar flow driven by the meridional electromagnetic force due to an electric current from a hemispherical electrode to a hemispherical cavity surface is studied using a multi-domain pseudospectral method. The most unstable azimuthal wave number is found as m = 4. Even in a low external magnetic field, the meridional flow in the main toroidal eddy changes its direction from counter-clockwise to clockwise due to the rotation in the azimuthal direction.
