Abstract In practical chemical applications, in order to improve the microwave heating uniformity, moving elements, such as mode stirrers, turntables and conveyor belts, have been widely used as an easy way to implement. However, different moving elements may have different shapes, modes of motion and moving speed, which makes the simulation of the heating process very difficult. In this paper, a stepping algorithm based on implicit function and level set method is proposed to simulate the microwave heating process of multi-component with unequal moving speed. The accuracy of the algorithm is verified by discrete method and experiments. Moreover, the model was used to analyze the heating process with different components at different positions and speeds. The effect of different materials of mode stirrers and shapes of heated sample on heating process were also compared. The researches show that the proposed model can effectively improve the heating uniformity and heating efficiency.

一种多运动元件微波加热过程耦合模型的仿真方法

摘要 在实际化工应用中，为了提高微波加热的均匀性，模式搅拌器、转盘和传送带等运动元件作为一种易于实现的方式被广泛使用。然而，不同的运动元件可能具有不同的形状、运动方式和运动速度，这使得加热过程的模拟非常困难。本文提出了一种基于隐函数和水平集方法的步进算法来模拟移动速度不等的多组分微波加热过程。通过离散方法和实验验证了算法的准确性。此外，该模型还用于分析不同部件在不同位置和速度下的加热过程。还比较了不同模式搅拌器材料和加热样品形状对加热过程的影响。研究表明，该模型能有效提高加热均匀性和加热效率。
