A Dielectric Heating Analysis Method With Accurate Rotational Motion of Stirrer Fan Using Nonconforming Mesh Connection

In order to evaluate the heating process of the target and the optimal structure of cavity in a furnace for dielectric heating, such as a microwave oven, the coupled analysis method composed of electromagnetic wave and heat conduction is a powerful tool for practical design. In this paper, we proposed the electromagnetic wave analysis method with a nonconforming mesh connection to take account of the rotational motion of the specific objects in a cavity resonator. The features such as a numerical error and convergence characteristics of the ICCOCG method were investigated, and the proposed method was applied to the dielectric heating analysis of the cavity resonator with rotation of stirrer fans.
