摘要
This paper is dedicated to deal with thermosolutal natural convection within an enclosure submitted to destabilizing heat and mass fluxes and confining an electrically conducting binary mixture. The cavity is bathed in an external magnetic field and Soret and Dufour effects are considered. An approximate analytical solution is derived, valid in the limit of a shallow enclosure and confirmed numerically by using a finite difference method. The results show the existence of six regions in 0 < theta < pi/2/(pi/2 < theta < pi) has a stabilizing/(destabilizing) effect with respect to stationary and sub-critical convections, regardless of the Hartmann number.
