| 中文摘要: |
| 针对离心泵叶轮叶片数较少的特点，将有限叶片数带来的滑移的影响引入S2流面反问题计算过程之中，提出了用滑移率修正在假定流动轴对称条件下确定的叶片安放角的做法.从而使S2流面反问题计算方法更接近于实际情况.文中给出了计算实例，并与现有的S2流面反问题计算结果进行了对比。 |
| 英文摘要: |
| A new method for inverse calculation of the blade S2 stream surface in centrifugal pump is established with the flow slip has been considered. The meridian flow is considered as a vortex flow and a slip rate correction is recommended to consider the effect of slip caused by finite amount of blade. An example is given for demonstration. |
