摘要/Abstract

摘要： 为了研究等离子体流动控制扩大压气机稳定性的流动机理，采用数值模拟方法研究了三种轴向等离子体激励方式对转速15200r/min，叶尖速度350m/s的高速压气机的扩稳特性。结果表明，对于轴向布置的三组等离子体激励器，其安装位置对单转子轴流压气机扩稳效果具有重要的影响，当第二组激励器位于叶尖前缘时扩稳效果最好。通过分析可知，等离子体气动激励能够显著改善叶顶负荷分布，抑制动量比的增加，改善泄漏涡的位置与形态，抑制泄漏涡向前缘的摆动，减小叶顶阻塞区域，最终扩大了高速轴流压气机的稳定工作范围。

Abstract: In order to study the flow mechanism of plasma flow control extend the stability of compressor on the high-speed compressor，numerical simulation is adopted to study the characteristics of stability extension about three kinds of axial actuation on compressor with rotational speed of 15200r/min and blade tip velocity of 350m/s. The results showed that the position of actuation has significant impact on single rotor axial compressor for three kinds of axial actuation，the maximum expansion of the compressor stability could be achieved when the medium actuation located in the tip leading edge. It is found that the plasma actuation can improve the distribution of the tip load，suppress the increase of the momentum ratio，improve the shape of the leakage vortex，restrain the swing of the leakage vortex toward the leading edge ，reduce the blocking area，and finally enhance the stability operation of the flow compressor.
