动叶尾迹强度明显减弱，叶背流动分离得到抑制，叶尖泄漏涡也得到了周期性的抑制。
The intensity of rotor wakes was reduced, flow separation on rotor suction side was suppressed and the tip leakage flow was suppressed periodically.
利用数值计算的方法研究了非定常尾迹对动叶气膜冷却效率的影响。
Numerical calculations were performed to investigate the effects of unsteady wakes on film cooling.
此外上游静子尾迹以及动叶尾缘出口膨胀波等也是产生转子叶片表面非定常力的因素。
In addition, the wake interaction of upstream blade row and the expansion wave at rotor exit also cause an unsteady force acting on the downstream rotor blade surface.
