| 摘 要： | 在一个亚音速的单级轴流压气机实验台上针对５种不同结构参数的斜沟槽型机匣处理进行了较为系统的实验研究。通过对总性能和基元性能，特别是叶片尖部流动的详细测量，证明了这种型式的处理机匣可以提高效率，但在稳定裕度上略有损失，并解释了其影响转子性能的机理。

| Abstract: | Five kinds of skew grooved cases with different geometric parameters were designed and tested on a rig of single stage axial-flow compressor.The detailed measurements of the overall performance and element performance,especially the blade tip flow prove that the treated casings enhance the compressor efficiency,but make slight loss of stall margin.According to analyzing the effects of each structural parameter on the compressor efficiency and stall margin,an optimization of primary geometric parameters has been found out.Then the effects of the grooved casing treatments on the performance of the compressor rotor have been revealed and some valuable conclusions have been reasoned out. |
