About the mathematical description of electromagnetic parameters of system flat inductor-detail
Classical cases of induction heating - cylinder and rectangular prism systems inductor-detail are researched in details and are shown with help of mathematical models, in accordance with mathematical description and methods for numerical analysis. Specifications are made by their practical realization of induction devices with different measures and parameters. In some partial cases induction devices for flat detail's heating are researched on the bases of experimental dependencies because of the complication of theoretic mathematical description. The main problem consists in distribution of the electromagnetic field and the processes connected with it. In such type of systems other method for analyze can be applied. Definition of system's electromagnetic parameters and with them connected distribution of electromagnetic field can be accomplished with integral dependence, applied for partial elements. The aim of this research is the theoretical current's distribution, flowing through circle formed detail to be obtained and compendious characters of system flat inductor-detail to be compared with the experimental results of laboratory model.
FEM MODELLING OF AN INDUCTION HEATING SYSTEM
The paper presents investigation of axisymmetrical induction heating system, consisting of two-layer disc-type inductor and heated detail. Two - dimensional coupled electromagnetic and temperature fields were analysed using FEM. The problem was solved as nonlinear and transient. The obtained numerical results have been compared to the experimental data for the magnetic flux and temperature distribution.... MORE
The present paper deals with numerical and experimental investigation of an induction heating system. It consists of two-layer disc-type inductor and heated detail. The numerical models of the coupled electromagnetic and temperature fields are based on the finite element method (FEM) and electromagnetic and temperature distribution have been obtained using ANSYS 9.0 software package. The results were compared to the experimental data for the temperature distribution in the laboratory experimental setup.
The aim of the work is investigation of possibilities for creating adequate field models at some control points of the induction system. They can be used in the next work, concerning special requirements for temperature distribution in the heating detail. So it is a first step for future solving of the optimization problem.
