摘要

圆柱形载荷在微波加热中很常见。然而，圆柱形载荷往往有一个热焦点，导致微波加热不均匀。本文提出了一种利用谐振环来减轻圆柱载荷热聚焦的新型微波加热方法。首先，建立了微波加热圆柱管的多物理场仿真模型，分析了圆柱管周围的谐振环对载荷温度分布的影响。随后，对带共振环和不带共振环的琼脂凝胶进行微波加热实验。与仿真结果一致，谐振环的使用使温度变化系数(COV)从1.064降低到0.793。此外，还通过仿真讨论了影响圆柱管加热均匀性的参数。

Mitigating Thermal Focusing in Microwave Heating of Cylindrical Loads by Resonant Rings

Cylindrical loads are commonly found in microwave heating. However, cylindrical loads tend to have a thermal focus, leading to uneven microwave heating. In this paper, a novel microwave heating method was proposed by employing resonant rings to mitigate the thermal focus of cylindrical loads. Firstly, a multiphysics simulation model for microwave heating of a cylindrical tube is established, and the influence of the resonant ring around the cylindrical tube on the temperature distribution of load was analyzed. Subsequently, microwave heating experiments of agar gels with and without resonant rings were carried out. In agreement with the simulation results, the use of resonant rings reduces the coefficient of temperature variation (COV) from 1.064 to 0.793. In addition, the parameters affecting the heating uniformity of the cylindrical tube were discussed through simulations.
