| 摘 要： | 给出了一种预测三维激盘／附面层相互作用诱导的流动起始分离的方法。研究结果表明：激波与附面层相互作用所诱导的二次流动是影响起始分离的重要因素。当来流相对马赫数大于１．５时，强的激波／附面层相互作用可能导致跨音风扇转子叶尖区域的流动分离。

| Abstract: | A model correlating flow separation with flow loss is proposed for predicting the incipient location and size of the flow separation in a transonic rotor.The flow fields of several rotors have been investigated with the model.The results show that the flow separation mainly occurs in the tip area owing to strong shock boundary interaction,and the incipient separation point is behind the shock location.The tip leakage flow vortex has a strong effect on the interaction between shock wave and boundary layer. |

| Keywords: | Three-dimensional flow Separated flow Shock wave-boundary layer interference |
