摘要
近年来 ,微波已被广泛用于流床进行各种工业处理 .本文利用FDTD方法通过求解流体中的Maxwell方程组和热传导方程模拟了微波与流动液体介质间的相互作用 ,计算了流动液体中的温度分布 ;并研究了波导型流床中的反射和透射与介质流速、倾斜度及流体直径之间的关系 .数值结果与实验结果相吻合 ,研究结果对工业应用具有指导意义 .
A fluidized bed combined with microwave is widely used in industry processing. Maxwell's equations of fluid combined with the heat transport equation are solved by FDTD to simulate the interaction between microwave and flowing liquid and calculate the field and temperature distribution in the flowing liquid. Moreover, reflection and transmission in the fluidized bed based on waveguide are also investigated with respect to the velocity of liquid, the obliquity, and diameter of the pipe, through which the liquid flows. Numerical results are in good agreements with experimental ones.
