摘要

感应加热会引起电磁和热现象的干扰。该问题的建模是基于麦克斯韦方程和热方程。本文提出了一种数值模拟与材料在加热过程中物理过程演变的耦合计算方法。为了解决计算时间问题，提出了一种间接耦合算法。该方法在MATLAB环境中实现二维情况，并利用PDE块中的工具。通过对铝坯再加热过程的建模和仿真，说明了该方法的应用实例。

Modelling and simulation of magneto-thermal coupling of induction heating processes

Heating by induction causes interference by electromagnetic and thermal phenomenon. The modelling of the problem is based on Maxwell's equations and the equation of heat. This article presents a method of numerical simulation coupling the calculation of physical process evolving in the material in the course of heating. An algorithm for indirect coupling is developed for resolving the problem of calculation time important for a big agreement between the thermal and electric constants. This method is implemented for the 2D case in the MATLAB environment and utilises the tools in the PDE block. An example application is illustrated by the modelling and simulation of reheating of an aluminium billet.
