Different common shapes of the RF-coil turns in induction heating systems were considered and corresponding results of electromagnetic fields, eddy currents and volumetric heat generation have been computed using a 2D finite element method. For calculations, rectangular (symmetric, asymmetric and shielded), circular, D-shape and -shape have been considered for the cross section of the coil turns. The obtained numerical results show the importance of cross section shape on the intensity and distribution of heat generation in the heating system.
Key words: Computer simulation, induction heating, finite element analysis, modeling, metals.
