摘要：

In this paper, we use two-phase mixture model and the 3D Realizable k-epsilon turbulence model to numerically simulate the advection secondary turbulence flow in a circular secondary clarifier. The PISO algorithm is used to decouple velocity and pressure. The results show that the model can provide a reference in designing sedimentation tanks.
