SIMULATION MODEL OF INDUCTION HEATING IN COMSOL MULTIPHYSICS

The induction heating phenomenon depends on various factors, making the problem highly nonlinear.The mathematical analysis of this problem in most cases is very difficult and it is reduced to simple cases.Other knowledge of induction heating systems is generated in production environments, but these trial-error procedures are long and expensive.The numerical models of induction heating problem are another approach to reduce abovementioned drawbacks.This paper deals with the simulation model of induction heating problem.The simulation model of induction heating system in COMSOL Multiphysics is created.The equivalent inductance and equivalent resistance of induction coilworkpiece coupling during heating process and temperature change for different parameters of AC current flowing through induction coil is obtained.In model, nonlinear electromagnetic and thermal properties of workpiece material are included.The simulation model provides essential information about processes ongoing in heated material.In order to verify the simulation model, the experimental measurements are made.
