【 摘 要 】
References(13)Cited-By(1)Visualization of flow and temperature fields and temperature fluctuation measurement in silicone oil imitating the CZ melt were carried out. The effect of Pr on the transition of flow mode in the liquid accompanied with crystal rotation were investigated experimentally and theoretically. As a result, it is found that there exists a critical Reynolds number Rec,2 for transition from axisymmetric periodic to three-dimensional aperiodic flow mode, as well as Rec,1 for the transition from steady-state to periodic flow mode. We also found that these two critical Reynolds numbers have limits for existence as a function of Pr.
