摘要:

应用CFD 数值模拟技术对城镇泵站侧向进水间原设计、加隔墩、加隔墩与圆柱三种方案进行流场信息对比。结果表明，侧向进水间原设计1# 进水间出现大尺度回流与低速区，设置隔墩后，大尺度回流消失，低速区范围大幅缩小；2# 进水间水流主流偏流，底层水流翻转，设置隔墩后，偏流与底层水流翻转现象得到好转，加入圆柱后，上述现象进一步好转，流态更加平稳；设置隔墩与圆柱结合整流措施，2# 进水间特征断面回流强度大幅下降，低速区进一步减小。

Abstract:

CFD numerical simulation technology is used to compare the flow field information under the three schemes: the original design，adding pier，adding pier and column.The results show that large scale flow with low velocity zone appeared in 1# intake chamber under the original design.Large scale backflow disappeared，the low-speed zone significantly reduced after setting separation piers;drift o f ma instream，t urnover o f bo ttom w ater a ppeared i n 2# i ntake c hamber unde r t he o riginal de sign.Drift and bottom water turnover phenom enon has been im proved after adding piers .T he phenom enon is further improved after adding column piers; the return strength of the characteristic section decreased sharply，and the low velocity zone is further reduced in 2# intake chamber after setting piers and column.
