摘　　要：基于计算流体力学方法研究管式膜过滤过程中液、固两相在膜管内的运动流态。以多孔介质模型和湍流模型分别模拟管式膜和连续相液体,采用离散相模型模拟计算并示踪离散相颗粒分布。Based on the computational fluid dynamics(CFD)method,the movement of liquid and solid phases in the tubular membrane filtra-tion process was studied.The porous medium model and turbulence model were used to simulate the tubular membrane and continuous phase liquid re-spectively,and the discrete phase model was used to simulate and trace the particle distribution of the discrete phase.
