腔体内壁脊形凹槽对微波反应器加热效率及均匀性的影响

摘要

提出在微波反应器腔体内壁设置脊形凹槽的优化策略,研究在保证加热效率的前提下提升微波加热的均匀性.利用有限元法仿真研究不同凹槽结构参数对微波反应器加热效率和均匀性的影响.研究结果表明:脊型凹槽结构能有效提升微波反应器的加热效率和加热均匀性.优化后微波反应器的加热效率达到98.75％,与微波腔壁光滑时相比,均匀性最大提升幅度达到58.54％.%A strategy that setting ridge groove surface in the inner wall of the microwave reactor is proposed for improving the heating uniformity without losing heating efficiency.The influence of the different ridge groove structure parameters on the heating efficiency and uniformity of the microwave reactor is simulated by using the finite element method.The result shows that the ridge groove structure can effectively improve heating efficiency and uniformity of microwave reactor.Heating efficiency of microwave reactor reaches 98.75％ after being simulated.When compared with the smooth cavity wall of the microwave reactor,the heating uniformity is enhanced up to 58.54％.
