Response of Temperature Oscillations in a Tin Melt to Centrifugal Effects

An experimental study was conducted on the flow and temperature oscillations of molten tin in a horizontal boat under centrifugation. A longitudinal temperature gradient was applied to an open boat containing molten tin so that convection was generated with a known direction of the basic flow. The experimental results demonstrated that both effects of centrifugal and Coriolis forces exist due to the rotation of the centrifuge. The former enhances the convection, decreasing the temperature gradient in the melt. The latter shows different influences on the flow stability depending on the rotation sense of the centrifuge. Temperature fluctuations in the melt are considerably retarded, provided the centrifuge rotation is in the same sense as the convection roll in the melt.
