Abstract
Convective instabilities generated in liquid cells, under earth’s gravity, for a destabilizing thermal gradient, can be removed by centrifugation. Experiments on molten tin show a reversible transition from an unstable to a stable regime, at a well defined value of the rotation rate. These observations can be understood by considering that the axial buoyancy force depends on both the density gradient and the acceleration generated along the axis of a fluid cell installed on a centrifuge.
