摘要：

A vertical enclosure, submitted to horizontal temperature and concentration gradients, is characterized by complex bifurcation phenomena. We are concerned by the situation where the opposing buoyancy forces due to horizontal thermal and concentration gradients are equal. In this work, the linear stability of equilibrium solution is studied in the case of infinite and rectangular cell. The structure of subcritical steady solutions has been studied numerically for several values of the aspect ratio of the enclosure.
