摘要/Abstract

摘要： 针对气固节涌床，在实验基础上，基于欧拉?欧拉双流体模型结合颗粒动力学理论，考虑Geldart A类颗粒聚团对气固间曳力的影响，采用修正后的Gidaspow曳力模型对气固节涌床进行数值模拟。结果表明，通过与实验结果及经验公式进行对比，修正的模型可准确合理地模拟流化床内节涌特性。表观气速0.09 m/s≤Ug≤0.39 m/s时，床层内部压力脉动标准偏差随表观气速增加而增加，流型由鼓泡转变为节涌直至节涌程度最大，床内气固流动主要受轴对称栓运动特性影响，床内压降、床层膨胀比、气栓平均上升速度、最大轴对称栓长度随表观气速增加而增加，最大轴对称栓产生位置随表观气速增加而降低；Ug>0.39 m/s后，床内压力脉动标准偏差随表观气速增加而降低，节涌程度降低至向湍动流态化流型转变，床内气固流动主要受壁面栓运动特性影响，增加表观气速，节涌床内压降变化幅度较小，气栓平均上升速度增加幅度加大，床层膨胀比及最大轴对称栓长度降低，最大轴对称栓产生的位置略有升高。
