The work herein employed COMSOL Multiphysics simulation and experiment to study the temperature distribution of water in a specially designed cylindrical microwave (MW) reactor with two magnetrons. A numerical model was developed by combining three modules including radio frequency (RF), fluid heat transfer, and nonisothermal fluid flow. The experimental results of the temperature distribution corresponded with simulative values. Additional experiments and simulations of a single microwave port as well as two different combinations of ports were carried out to confirm the uniformity of the results. Results show that two parallel waveguides are better than both a single waveguide and two perpendicular waveguides in terms of uniformity and efficiency at the same incident power.

多波导微波反应堆中水的温度分布建模

本文的工作采用COMSOL Multiphysics模拟和实验研究了带有两个磁控管的特殊设计的圆柱形微波（MW）反应器中水的温度分布。通过组合三个模块（包括射频（RF），流体传热和非等温流体流动）开发了一个数值模型。温度分布的实验结果与模拟值一致。对单个微波端口以及端口的两种不同组合进行了额外的实验和模拟，以确认结果的一致性。结果表明，在相同的入射功率下，两个平行波导在均匀性和效率方面均优于单个波导和两个垂直波导。
