Three-dimensional flow visualization experiments were used to observe the transition from axisymmetric to non-axisymmetric flow of molten silicon in the CZ crystal growth configuration at specific crucible rotation rates. Non-axisymmetric flow shows characteristics of the baroclinic instability when the flow pattern is observed from a rotating viewpoint. The transition from axisymmetric to non-axisymmetric flow due to the baroclinic instability is characterized by using two non-dimensional numbers, the Thermal Rossby number (Rot) and the Taylor number (Ta).
