Abstract
Mathematical modeling of Induction heating process is done by using 2D axisymmetric geometry. Induction heating is coupled field problem that includes electromagnetism and heat transfer. Mathematical modeling of electromagnetism and heat transfer is done by using maxwell equations and classical heat transfer equation respectively. Temperature dependent material properties are used for this analysis. This analysis includes coil voltage distribution, crucible electromagnetic power, and coil equivalent impedance at different frequency. Induction coil geometry effect on supply voltage is also analyzed. This analysis is useful for designing of induction coil for melting of nonferrous metal such as gold, silver, uranium etc.
