A schematic diagram of crystal growth by directional solidification is shown in Fig. 18.8. Analyze the various flow mechanisms and indicate how they affect the heat transfer, the movement of the frozen front, and the shape of the melt-solid interface. Problems of this type are important in production of solar cells.
