摘　　要：基于CFD手段,采用雷诺时均N-S方程和表示自由水面的VOF模型,并以RNGk-ε双方程紊流模型封闭方程组,首先模拟了泵站开敞式常规进水池的水流流动,针对进水池后壁流线被压缩和进水池后壁两边角出现水流旋涡的现象,提出了对后壁体型的一种改善措施,从而有利于水流条件的改善,提高了水泵的工作效率。研究结果可为相关设计和实践应用提供参考。Based on the CFD method, the Reynolds average N-S equations and express the free surface of the VOF model, and close to the RNG κ-ε equation turbulence model equations the flow characteristics in routine open pump sumps are simulated. A kind of improvement measure is proposed on the shape of the after-wall, thereby improving conditions for the sump water and the efficiency of the pumps. The findings serves as a reference for the design and practical application
