| 摘 要： | 本文利用CFD商用软件PHOENICS,模拟平流式二沉池内的流线和速度分布.结果表明池内的实际流场与理想沉淀池之间存在着很大的差异,特别是在挡板前后存在着两个极为明显的涡流区,影响二沉池的沉淀效果.并且还考虑了不同的回流比对二沉池流态产生的影响.

| Abstract: | In this paper, the business CFD software PHOENICS is adopted to simulate the velocity and streamline distribution of a rectangular sedimentation tank. The results indicate that the real flow pattern of the tank is greatly different from that of the ideal sedimentation tank, There are two obvious eddy fields existing around the baffle plate that influence the settling effect of the tank, and the different reflux ratio which influences the flow pattern of the sedimentation tank is also considered. |
