Experimental study on the effect of crystal and crucible rotations on the thermal and velocity field in a low Prandtl number melt in a large crucible

Transition times from one flow field to another fully developed flow field when crucible rotation rates were suddenly changed were also measured. Transition times of the temperature field were also measured, which takes a longer time than the time of velocity transition. The transition time is decreased as the crucible rotation rate is increased. Transition of temperature has two different modes such as regular and irregular transition.
