Notes:
In this work, a numerical model for induction heating is proposed. The heating processconsiders only interaction of electromagnetic effects and heat transfer, and is represented by anunsteady heat diffusion equation. The numerical simulation of the process is performed using afinite volume method in which the induction heating is represented by a volumetric heat sourceterm. The heat source term is evaluated analytically using principles based on Faraday’s and Biot-Savart laws. The technique is applied to the case of induction heating of a cylindrical A356aluminum alloy billet. The model predicts magnetic flux density and temperature distribution duringthe heating process. The effects of process parameters, such as frequency and current density, on thetemperature distribution are also studied. The results show that nearly uniform distribution oftemperature can be achieved when the billet is heated slowly with low frequency and low supplycurrent density
