On Generalized MHD Double-Diffusive Convection in Completely Confined Binary Fluids

The hydromagnetic instability of binary, Boussinesq and electrically conducting fluids completely confined in an arbitrary region bounded by rigid walls in Stern's geometry, with both the Soret and Dufour effects included has been studied in the present paper. Some general qualitative results concerning the character of marginal state, stability of oscillatory motions and limitations on the oscillatory motions of growing amplitude, are derived. The results for the horizontal layer geometry in the present case follow as a consequence.
