以引黄泵站工程田山一级泵站的更新改造为背景，运用三维紊流数值模拟技术，基于大型计算流体力学软件Fluent为平台，对田山一级泵站4号前池、进水池内部水流流态进行了数值计算，揭示了泵站前池水流特性，并预测了泵站前池进水池流态分布。研究结果为泵站的改造提供了技术支持，对保证泵站的安全运行、优化设计具有重要的指导意义。

In consideration of the transformation of Tianshan pump station in Yellow River pump station project, a three-dimensional turbulent flow simulation technique was applied to simulate the flow patterns in the No.4 forebay and intake pool of Tianshan pump station based on the large-scale computational fluid dynamics software, Fluent. The results revealed the flow pattern in the forebay and predicted the flow distribution in the intake pool. The research results can provide a theoretical basis for the transformation of pumping stations, and thus ensure the safe operation and optimal design of pump stations.
