摘要(Abstract)：

采用欧拉双流体模型模拟短接触旋流反应器内气固两相流动,加载无反应组分输运方程计算入口混合区内气固停留时间分布(RTD)。根据各截面上下行流率分配,定义了截面返混比,并考察了入口结构型式对气固返混特性的影响。研究结果表明,反应器混合区内固体催化剂的停留时间比气体小;气体在入口混合区内返混程度比固体颗粒显著,颗粒接近平推流;气体截面返混比为0~0.5,且随着轴向位置增大呈现先增加后减小的趋势;轴向入口设导向叶片增大了反应器混合区内气体轴向返混;与直切式和斜上切式结构相比,斜下切式结构反应器混合区气体返混程度较弱,有利于催化裂化反应。

关键词(KeyWords)： 旋流反应器;计算流体力学;停留时间分布;返混
