FLOW FIELD AND TEMPERATURE FILED SIMULATION OF DIRECTIONAL SOLIDIFICATION OF POLYCRYSTALLINE SILICONINGOTS

摘要：

A simplified model for directional solidification of polycrystalline silicon has been built in this study. On the base of setting thermophysical properties of polycrystalline silicon and boundary conditions of the model, the three-dimensional flow field and steady-state temperature field of directional solidification of polycrystalline silicon under different conditions was calculated by using a commercial software package, JSCAST. The influence of the ingot size, the heat transfer coefficient at the interface of ingot/mould wall and water on the directional solidification process have been analyzed.
