| 摘 要： | 将分离与损失相关联，提出了利用转子进出口参数来确定跨音风扇转子内部分离流动的方法。应用该方法对几个转子流场计算的结果表明，在转子的叶尖区域，由于强的激波与附面层相互作用，使得流动在激波后不久便发生分离。叶尖漏流涡可能对激波与附面层的相互作用诱导流动分离有较大影响。

| 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. |
