VELOCITY FIELD OF THERMOCAPILLARY CONVECTION IN LIQUID BRIDGE OF HALF FLOATING ZONE
半浮区液桥热毛细对流速度场特征

The velocity distribution of flow field in liquid bridge is an important aspect in the thermocapillary convection driven by the gradient of free surface tension in liquid bridge. This paper presents the velocity variation for typical liquid bridge shape and applied temperature difference. The experiment results agree with the numerical simulating results. It is indicated that the vortex in the liquid bridge splits into two when the liquid bridge is slender enough.
