本工作已经进行了表征圆柱形流化床中的三相流的动力学，运行在均匀的气泡流和非均相流条件下，使用CFD（计算流体动力学）模拟。本文对三相流化床沿着流态进行了参数研究。对空气-水-玻璃微珠在H = 0.6 m，Di = 0.1 m，ds = 0.05 m的流化床中的流动进行了模拟，研究了流化床中的流型。欧拉欧拉，三相模拟k-？采用CFD-6.2.16流动模拟软件对液相进行了湍流模拟，重点研究了气-液-固三相流动的动力学特性。对三相流化床内的流型进行了详细的研究，并以等值线图的形式给出了流型。所得结果有助于理解流化床内气液固三相流动的动力学特性，为进一步发展三相流CFD模型奠定了基础。
The present work has been carried out to characterize the dynamics of three-phase flow in cylindrical fluidized bed, run under homogeneous bubble flow and heterogeneous flow conditions using CFD (Computational Fluid Dynamics) simulation. The investigation has been done to study the flow pattern of three-phase fluidized bed along with parametric studies. The simulations were performed for air-water-glass beads in a fluidized bed of H = 0.6 m, Di = 0.1 m and ds = 0.05 m to study the flow pattern. Eulerian-Eulerian, three-phase simulations with k-? turbulence for liquid phase were carried out using the flow simulation software CFD-6.2.16, with a focus on characterizing the dynamics properties of gas-liquid-solid flows. Detail study of the flow pattern in three-phase fluidized bed has been carried out and the flow pattern has been presented in the form of contour plots. The results presented are useful for understanding the dynamics of gas-liquid-solid flows in fluidized bed and provide a basis for further development of CFD model for three phase systems.
