Influence of combined electromagnetic fields on the heat/mass transfer in the Bridgman process

The influence of combined magnetic fields (travelling and rotating) on the characteristics of heat/mass transfer with an aim to obtain the needed profile of the interface is considered, that is a necessary condition, which insures the homogeneity of single crystal content. The crystallization process of a cylindrical sample is considered. It was presumed that the sample moves with a permanent velocity towards the cold part of the heater and a partial-linear temperature distribution characteristic to the Bridgman method was set in along the heater's length. Permanent temperature values were set in on the top and bottom edges of the calculation mesh. It has been shown that combinations of dif…
