초록
An experimental investigation on flow pattern was carried out in molten Woods metal using an incorporated magnet probe to determine the velocity field in a Woods metal model of Czochralski crystal growth system. The local velocities in Woods metal were obtained 3-dimensionally at numerous positions of large crucible by measuring the voltage induced in the melt. Since there have not been a lot of the model experiments on the velocity distributions in the large size of melt with low Prandtl number for Czochralski crystal growth system, the present paper aims to give useful guidelines for e analysis of fluid flow in Czochralski growth system.
