| 摘 要： | 本文利用高频响动态压力传感器，在文献［１］的基础上，对ＷＰ１１压气机转子叶尖间隙 流场进行了流场测量。测试包括三个转速多个节流条件下的间隙流场。测试结果表明：激波总体位 置随节流加深而向上游移动，但吸力面最小压力点基本维持在４０％或２０％弦长处不变。当激波位 置在该点之后时，二次漏流直接冲击激波结构；当激波位置在该点之前时，激波结构基本只受前缘 漏流的影响。 |

| Abstract: | High frequency response unsteady pressure transducers were used to investigate tip clearance flow structures in a transonic compressor rotor. Shock structures and their interactions with tip clearance leakage flow are studied in the present paper from open throttle operating condition to stall for three corrected rotating speeds. The position of minimum static pressure locates at 40% or 20% chord length, and keeps the position for the different operating conditions, although the passage shock moves upstream with closing outlet throttle. When the impacting point of shock on suction surface locates behind the minimum pressure, secondary leakage flow distorts the passage shock directly, otherwise, leading edge leakage flow effects much upon the passage shock wave. |
