Convection of a weakly ionized plasma in a strong magnetic field: non-axisymmetric waves

Abstract

Convective instability of a weakly ionized plasma contained in a narrow gap between two metal cylinders is studied considering non-axisymmetric waves. The case with the applied magnetic field in the azimuthal direction due to a central electrode is treated. The results show that the non-axisymmetric waves are more stable than their axisymmetric counterparts.
