摘　　要：泵站侧向进水前池中易形成不良流态,为了改善不良流态,以Fluent为平台,采用SSTk-ω湍流模型,研究了某侧向进水排涝泵站的进水水力特性,通过定性与定量分析,得出了最佳的导流墩布置方案,有效地改善了该泵站前池的不良流态.分析结果表明,侧向进水前池中,由于水流侧向流入,进水前池各纵向断面的流态不是对称分布的,设置导流墩分配水流时,应根据工程实际情况适当调整;针对漩涡产生的位置设置导流墩,能有效地消除漩涡,改善进水流态.Poor flow parttern always happens in the forebay of side inlet pumping station. In order to improve the flow parttern, a side inlet pump station has been studied by using theSST κ-ω turbulence model in Flu ent. A best scheme of diversion piers layout is obtained by qualitative and quantitative analysis; therefore the flow parttern is improved remarkably. The results indicate that due to the flow parttern is not symmetrical in side inlet pumping station, the scheme of diversion piers should be arranged according to the specific situation of project; the diversion piers aimed at the swirl could remove the swirl effectively so as to improve the flow parttern.
