In the present study, the fluid flow in cold crucible and its effects on solute transport were numerically and experimentally investigated. It was found that the coupled effects of alternating magnetic fields and the configuration of cold crucible induce a vigorous three-dimensional melt flow. Further, solute transport results indicate that the three-dimensional flow contributes to more efficient melt stirring, and the stirring efficiency for obtaining uniform melt is improved by 77.5 pct compared with only meridional flow.
