Exploration of Microwave Heating Characteristics of Contacted Multiple Pellets by Numerical Simulation
摘要
Microwave heatingMicrowave heating can reduce the reduction of difficulty and energy consumption. In this study, the microwave heatingMicrowave heating process of single pellet and multiple pellets were simulated using the software COMSOL. For a single pellet, the maximum electric field strength inside the sample is 11800 V/m, while the maximum magnetic field strength is 63.3 A/m. The highest temperature reached 833 ℃. For multiple pellets, the maximum electric field strength inside the sample is 33900 V/m, while the maximum magnetic field strength is 97.2 A/m. The highest temperature reached 502 ℃. It is necessary to set an appropriate loading mass and microwave power to enhance microwave efficiency.
