摘　　要：为了提升潜水轴流泵的性能,了解其内部流动规律,采用标准k-ε双方程紊流模型和压强连接的隐式修正SIM PLEC算法,对潜水轴流泵全流道进行了CFD分析.得出了流道内各速度矢量、压力分布规律,并提出相应的改进建议.In order to improve the performance of submersible axial flow pump and master the rule of its inside flow, by means of the standard k-ε turbulence model and SIMPLEC algorithm, a CDF analysis was made of the full flow passage in this type of pump. The vectors of velocity and the rule of distribution of pressures on surfaces of blade and guide blade were found. Suggestions were made to ameliorate its performances.
