Thermosolutal instability of a partially-ionized plasma (Q1116788)

The thermosolutal instability of a partially-ionized plasma in the presence of a horizontal magnetic field is considered to include the frictional effect of collisions of ionized with neutrals. The sufficient conditions for non-existence of overstability are derived. The solute gradient and magnetic field introduce oscillatory modes in thermosolutal convection which were non-existent in their absence. The magnetic field and stable solute gradient are found to have stabilizing effects whereas sollicional effect of ionized with neutrals is found to have destabilizing effect on thermosolutal instability of a partially ionized plasma.
