摘要/Abstract

摘要： 可调进口导叶和叶片角向缝处理机匣都能扩大压气机的稳定工作范围，为了分析同时采用这两种措施对压气机稳定性的影响及二者之间相互作用的机理，在单转子轴流压气机实验台上对不同导叶弯角下实壁机匣和叶片角向缝机匣进行了详细的实验测试。同时，对导叶弯角为+10°的每一种机匣结构和导叶0°的实壁机匣结构进行了数值模拟，数值模拟结果与实验结果符合良好，相对于导叶0°的实壁机匣，实验及数值模拟结果均表明，导叶正弯角结合叶片角向缝机匣处理结构能更好地扩大压气机的稳定工作裕度。对转子流场进行对比分析可得，导叶正预旋能抑制叶背气流的分离，提高压气机的稳定工作范围，但仍然没有改变转子叶尖部诱发失速的流动现象，而叶片角向缝主要是通过对叶顶气流的抽吸作用抑制了间隙泄漏流达到扩稳效果，因此耦合时能独立发挥各自的扩稳作用，从而能获得比单独使用任何一种方法都要更大的稳定工作范围的提升。

Abstract: The variable inlet guide vanes and axial skewed slots casing treatment are effective measures that can extend the operating range of compressor. In order to analyze the mechanism of the interaction of these two measures，the different guide vanes angle with original smooth wall as well as slots configuration were tested on a single-rotor compressor. At the same time，the guide vane angle of 10° with each casing configuration and the guide vane angle of 0° with original smooth wall configuration are simulated. The results of experiment and calculation show that the introduction of these two kinds of measures can gain greater improvement of the stall margin. The difference of the flow fields of the rotor was analyzed. The positive angle of the inlet guide vane can weaken the separation of suction part flow，but it does not change the phenomenon of the stall induced at tip of the rotor blade. The axial skewed slots can weaken the structure of tip leakage vortex to get the improvement of the stall margin. The different mechanism of these two measures can make sure that using these two measures at the same time can gain greater improvement of the stall margin.
