Numerical Simulation for Optimizing Flow Guide Structures for Humidifying Activation in Reactors

该文用欧拉 拉格朗日法模拟烟气增湿活化反应器内稀疏气固两相流 ,对气相流场及颗粒相数密度分布分析表明 ,烟气进口位置及进口处的导流设备对反应器内颗粒分布影响显著 ,以双层弧型板做导流设备能够较好地改善其流场和颗粒相分布。图 8参 5。

The paper presents a simulation of lean gas solid two phase flow. In reactors, for the humidifying activation of flue gas, with the help of the Eule lagrange method. An analysis of the gas flow field and the density distribution of the solid particle phase shows that the particle distribution within the reactor is remarkably affected by the position of the inlet and its flow guiding structure. Double layer and shaped guide vanes can satisfactorily improve the flow field and the particle phase distribution. Figs 8 and refs 5.
