摘要
在微波化学研究中 ,对反应溶液温度变化的模拟和控制具有十分重要的意义。利用模拟微波在TEMcell中与试管内的化学反应溶液相互作用 ,以有限时域差分 (FDTD)法为基础 ,结合蛙跳技术 ,计算了微波化学反应过程中的温度分布及变化情况。有效缩短了模拟计算时间 ,数值计算结果与实验测量数据得到很好的吻合。
In the research of microwave chemistry, the temperature simulation and control of the chemical reacting solution is very important. In this paper, a new leapfrog technique based on the finite-difference time-domain (FDTD) method is used to simulate the interaction between microwaves and reaction solution in test tube placed in the TEM cell. The temperature and its variety with reaction time are calculated. Good agreement can be seen between the measured and calculated results.
