摘　　要：文中以吉林省老白沙滩泵站改造工程为例,针对侧向进水泵站前池结构形式进行方案对比研究。基于不可压缩流体的连续性方程、雷诺平均纳维-斯托克斯方程和标准k-ε湍流模型,采用CFX软件,对不同方案进行数值模拟计算。研究结果表明:矩形前池与收缩前池的水力性能差异极小,分配流量性能矩形前池略优。研究结果可为类似工程提供参考。Taking old Baishatan Pump station reconstruction project in Jilin Province as an example, this paper makes a comparative study on the structural forms of fore pond of lateral inlet pump station. Based on the continuity equation of incompressible fluid,Reynolds mean Navier-Stokes equation and standard k-ε turbulence model, CFX software was used to simulate the different schemes. The results show that there is little difference in hydraulic performance between rectangular front tank and shrinking front tank, and rectangular front tank is slightly better in flow distribution performance. The research results can provide reference for similar projects.
