Abstract

Global simulations were performed for a large-scale CZ-Si growth system, in which three models were tested to predict the turbulent melt flow. The three turbulence models are the standard k-ε turbulence model using wall functions at solid boundaries, a modified two-layer k-ε turbulence model in RANS method and the standard Smagorinsky SGS model in LES method, respectively. The comparison of the simulation results obtained with these different models showed that each turbulence model has its own features in prediction of the melt convection and the melt-crystal interface shape in a large-scale CZ-Si growth system.
