基于颗粒动理学和化学动力学理论,建立化学链燃烧计算模型,数值模拟了耦合反应器内化学链燃烧过程,获得了反应器内流场特性和各组分分布规律,并很好地捕捉到了空气反应器中颗粒呈现出的非均匀环核流动结构。模拟结果同时给出了反应器中温度分布规律以及各出口颗粒质量流率和各组分浓度随时间的变化,为耦合反应器的设计优化提供了一定的依据。 Based on the theory of particle kinetics and chemical kinetics, a mathematical model of chemical combustion was set up to simulate the combustion process of chemical chain in the coupled reactor. The characteristics of flow field and the distribution of each component in the reactor were obtained. Particles in air reactors exhibit a non-uniform ring core flow structure. The simulation results also give the temperature distribution law of the reactor and the change of particle mass flow rate and concentration of each component over time, which provides a basis for the design optimization of the coupled reactor.
