摘要
工业应用中的快速流化床一般不能直接对固相速度进行调控，属于B类操作．本文采用一维双流体模型与存料量方程相结合的方法可以计算B类操作时的上升管内具有浓、稀两相特征的轴向空隙率分布，模拟与实验结果较为吻合．
The fast fluidized beds in industrial application belong to type B, and the solidvelocity can not be controlled. The method of combining the 1-D two-fluid model with aninventory equation was used to simulate the axial voidage profile, which is a typical phenomenonin the riser of a fast fluidized bed. Satisfactory result were achieved.
