Résumé :
|
The instabilities of a fluid layer of a binary alloy, cooled from above and consequently frozen at bottom, are considered. The released light material at the freezing interface is diffused by pressure and composition gradients. As a result of a small cooling rate and a large thermal diffusivity, the thermal effect is inefficient, compared with the compositional one, for driving a possible convection.
