摘要
根据对提升管中气固两相流动行为的影响对出入口结构进行分类，归纳为出入口结构的流动约束程度和出入口开孔位置安排方式两类结构因素，其分别影响提升管中轴向流动特征和径向参数分布。
Many different configurations of entrance and exit in circulating fIuidized beds have been studied. According to their effects on the structure of gas-solid two phase flow in risers, the entrance and exit effects can be classified as the restriction on the solids circulating flow and the arangement of open area. The former mainly influences the axial voidage distribution and the latter has effects on the radial voidage profiles and solids backmixing.
