摘　　要：将絮凝过程与计算流体力学结合起来,综述了絮凝过程中计算流体力学的应用研究,用计算流体力学对絮凝过程中絮凝池流场进行模拟分析,得到絮凝过程速度云图、压力云图、浓度梯度图,直观反映了絮凝过程。这种参数化建模方式简化了研究过程,可对絮凝工艺研究与设备优化提供参考依据。This paper reviews the application of computational fluid dynamics（CFD） in the flocculation process.CFD is used to simulate and analyze the flow field and velocity field in flocculation tank during flocculation process.The speed cloud chart,pressure cloud chart and concentration gradient map of flocculation process are obtained,which reflects directly the flocculation process. This parameterization modeling method can simplify research process and provide references for the process research and equipment optimization of the flocculation process.
