Abstract
We analyze here the flow in a horizontal closed cylinder of aspect ratio 2, induced by both an axial temperature gradient and the rotation about its axis. A Prandtl number representative of molten metals at high temperature is considered. We have characterized the symmetric basic states and analyzed their stability when the temperature gradient increases in a region of moderate values of rotation rates, in which the two driving effects, natural convection and rotation, are comparable. The bas...
