Abstract This paper aims to investigate the heating behaviors of Y-TZP arrays under microwave irradiation. In this study, a three-dimensional numerical model of the microwave heating system was developed by COMSOL Multiphysics software. The numerical model was verified by microwave heating experiment, and the average root means square errors (RMSE) between the simulation and experimental data also confirmed the reliability of the model. The varying position and arrays of materials were applied to predict and visualize the three-dimensional distribution of the electromagnetic field and temperature during the microwave heating process. The results show that the temperature field distribution in microwave cavity was highly sensitive to the dielectric materials, the arrangement of the Y-TZP array interfered with the distribution of standing waves. The results can serve as references for the study to design and optimize the ceramic’s application in terms of microwave heating.

多物理场系统下Y-TZP陶瓷的微波诱导加热行为

摘要 本文旨在研究Y-TZP阵列在微波辐射下的加热行为。在本研究中，使用 COMSOL Multiphysics 软件开发了微波加热系统的三维数值模型。通过微波加热实验对数值模型进行了验证，模拟与实验数据的均方根误差（RMSE）也证实了模型的可靠性。应用不同位置和材料阵列来预测和可视化微波加热过程中电磁场和温度的三维分布。结果表明，微波腔内的温度场分布对介质材料高度敏感，Y-TZP阵列的排列干扰了驻波的分布。
