Résumé

The stability of the Soret-induced convective flow of a binary mixture of non-reacting components to traveling thermosolutal perturbations is studied. Dependence of the threshold value of the Prandtl number, at which the viscous thermal mechanism of the conductive state crisis becomes most dangerous, on the separation ratio is obtained. For positive Soret effect, the range of Prandtl number values where the thermal waves are completely suppressed is discovered.
