摘　　要：为了更好地了解化学链燃烧过程中气固流动的特点以及反应特性,基于化学动力学理论和颗粒动理学理论,考虑高颗粒浓度下摩擦应力的影响,运用双流体模型,对燃料反应器内化学链燃烧过程进行数值模拟,得到了燃料反应器内流场特性以及温度场分布规律。模拟结果同时得到了反应器内颗粒所形成的内循环流动结构。To understand fluid dynamic behavior of the gas - solid flow and reactive characteristics of chemical looping combustion, the gas - solid flow process and chemical reaction in the fuel reactor were simulated using a two - fluid model with kinetic theory of granular flow and chemical kinetics. The fric- tion stress of particles was considered to account for individual particles interaction with multiple neigh- bors through sustained contact at high particle concentrations. Flow characteristics of particles and the distribution of temperature were obtained. The circulation of particles in the bed was observed.
