3D dynamic simulation of heat transfer and melt flow in an inductively heated crystallization furnace for mc-silicon with PID temperature control
A heat transfer model of a semi-industrial induction furnace has been build, using a 3D finite element model in order to analyze the entire process cycle, based on the heating, melting, solidification and cooling phases of a multi-crystalline square ingot. In the modeling of the entire process, heat...
Dynamic simulation of impurity transport and chemical reactions in a Bridgman furnace for directional solidification of multi-crystalline silicon
Numerical results from a dynamic simulation of impurity transport and reactions in a Bridgman furnace for directional solidification of multi-crystalline silicon are presented and compared to experimental results. The simulation includes the calculation of the thermal field, melt and gas flow veloci...
Optimization of silicon crystallization in a Bridgman growth furnace by numerical modeling
A heat transfer model of a semi-industrial furnace has been build, using a 3D FEM model in order to analyze the crystallization phase of a multi-crystalline square ingot. In the modeling of the solidification process heat transfer phenomena, such as radiation and conduction in the furnace have been ...
Effect of flow pattern on the segregation of impurities in vertical Bridgman growth of multi-crystalline silicon
Numerical experiments are used to study thermally driven flow during directional solidification of multi-crystalline (mc) silicon. A solid–liquid (s–l) interface shape was imposed by varying the absolute value and the direction of the radial temperature gradient in the melt. The flow pattern and the...
