Status and perspectives of the multiphysical simulation of induction kitchen plates

Abstract

Induction cookers are a relatively new class of modern electrical household appliances – kitchen electric stoves that heat metal dishes with eddy currents generated by an electromagnetic field with a frequency of 20-100 kHz. Of considerable interest is the study of multiphysical (electromagnetic, thermal, and mechanical) processes occurring in induction cookers during their operation, as well as the development of methods for calculating and designing their structural elements. The results obtained should be intended for use in the practice of designing domestic induction cookers, as well as in the educational process for training specialists in the relevant curriculum. The number of published papers devoted to computer simulation of processes in induction cookers is many orders of magnitude less than the number of publications on the issues of well-developed numerical analysis of multiphysical phenomena in industrial induction heaters. The paper presents a review and analysis of publications, mainly published abroad devoted to multiphysical computer modeling of electromagnetic and thermal processes and phenomena in induction cookers and heated dishes. The directions for further research have been proposed: it is advisable to take into account, when applying the finite element method, the dependencies of the electrophysical and thermal properties on temperature, as well as the nonlinear magnetic properties (main magnetization curves) of ferromagnetic materials. Mathematical modelling of the distribution of coupled fields should be started in a two-dimensional formulation (a much more complicated three-dimensional formulation and the corresponding software can be used later to refine the results).
