摘要
通过采用外部声激励的方式,在低速轴流压气机内研究非定常尾流撞击效应对压气机流场结构以及时均气动性能的影响。主要包括:低速轴流压气机实验台的流场调试;流场的稳态、动态测量;实验数据的处理和分析。实验结果表明:当发生尾流撞击耦合效应时,压气机内部流动的时空结构以及时均气动性能均得到较大提高。
Influence of the wake impact effect on the flow field and its average performance in a low speed axial-flow compressor was investigated by using external acoustic excitations. Main focus is on the flow field calibration, the steady and dynamic performance measurement and the analysis of the experimental data. The results indicate that the time-space structure and the average aerodynamic performance can be improved greatly when the couple of wake impact effect is occurred.
