چکیده
In this paper, a magnetic flux concentrator (MFC) is reported, and its geometry effect on the induction heating process has been calculated in a Czochralski crystal growth system using the 2D finite element method. We have considered 8 cases; for the first case, the system has no magnetic flux concentrator. By solving Maxwell's equations, quantities such as distribution of electromagnetic fields as well as heat and its rate (in coil and crucible) have been computed. The results show that the presence of the magnetic flux concentrator and its different geometries has dramatic effect on the above mentioned parameters. The volumetric heat rate in the crucible bottom significantly increases possibly due to the presence of solidified melt. In addition to the crucible bottom with different MFC forms, the distribution and value of generated heat in the crucible wall change strongly.
