Induction Heating Devices with A Moving Inductor of Low and High Frequency

Abstract

This work presents a numerical simulation model using comsol multiphysics developed for coupling the electro magneto and thermal phenomena taking place in induction electromagnetic heating devices with a moving inductor. All three electro magneto and thermal models are time dependent and take full account of the electro magneto and thermal non linear effects especially with ferromagnetic and non ferromagnetic materials. The numerical simlation which has been used to solve the electro magneto and thermal problem is based on a finite element method with a comsol multiphysics in the moving inductor, workpiece and air. The maxwell’s equations and the heat transfer equations are solved in the moving inductor and workpiece using an electromagnetic model of low and high frequency. Non-lineair model has been applied successfully to several positions of inductor and workpiece.By taking these factors into consideration, thermal comfort can be effectively managed in induction heating, ensuring safe and efficient operation for both operators and equipment.
