Numerical model of turbulent CZ melt flow in the presence of AC and CUSP magnetic fields and its verification in a laboratory facility

The paper describes a numerical simulation tool for heat and mass transfer processes in large diameter CZ crucibles under the influence of several non -rotating AC acid CUSP magnetic fields. Such fields are expected to provide an additional means to influence the melt behaviour, particularly in the i ndustrial growth of large diameter silicon crystals. The simulation tool is based on axisymmetric 2D models for the AC and CUSP magnetic fields in the whole CZ facility and turbulent hydrodynamics, temperature and mass transp ort in the melt under the influence of the electromagnetic fields. The simu lation tool is verified by comparisons to experimental results from a labor atory CZ setup with eutectics InGaSn model melt. (C) 2001 Elsevier Science B.V. All rights reserved.
