| Abstract: | A novel designed microwave heating device feed by solid generator was present in this research. The coupling interaction of electromagnetic field, thermal field and fluid field were analyzed mathematically, numerical calculation result by self-programmed Finite Different Time Domain method and COMSOL Multiphysics commercial software was also given. The final experiment results verified the theory derivation and numerical calculation. This subtle device improves the microwave energy absorption and temperature uniformness substantially, which can be predicted it with a great potential application in industrial, especially in low lossy material heating. |
