| 摘 要： | 综述了有关循环流化床内气固两相流动的数学模型,包括欧拉坐标系下的两相流体模型以及近年来兴起的颗粒动力学双流体模型、基于拉格朗日坐标下的颗粒轨道模型、被很多学者应用的“小室模型”等,对由这些基本模型发展出的更新的一些模型进行了分类,并比较了其各自优缺点,提出了可能的发展方向。

| Abstract: | Mathematical models on gas and solid phase fluidization in CFBs were summarized,including two-phase flow models by Eulerian approach,double flow models which were very popular in recent years based on kinetic theory of particulate phase,particle track model by Lagrangian approach and cell models.Some new developed models were classified,and their advantages and disadvantages were compared.The future direction was put forward. |
