不同叶片安装角的轴流泵内部流动特性分析

摘要

结合浙江省某更新改造泵站,在三维湍流Navier-Stokes控制方程的基础上,采用标准k-ε模型和SIMPLEC算法,对不同叶片安装角的轴流泵内部全流道流场进行了数值模拟,分析讨论了不同安装角下的叶片静压分布图、叶片相对速度分布图,对轴流泵的扬程进行了预测,最后给出了该轴流泵合适的叶片安装角.%Based on the 3D turbulent Navier -Stokes Equation, the internal flow of axial-flow pump with different blade mounting degree are simulated by using standard k -e turbulent model and SIMPLEC algorithm. The static pressure and relative velocity fields of blade are analyzed, and the head of pump is forecasted. The appropriate blade mounting degree is finally proposed.
