摘要
讨论了轴流压气机环壁边界层的流量阻塞效应和减功效应，提出了一种工程上可以简便适用于轴流压气机设计和分析用的新的阻塞系数和减功系数计算方法，并应用于二台导叶可调及不可调的十多级轴流压气机变工况的性能分析计算，结果与实验值吻合良好。
The effect of blockage and work lost caused by end wall boundary layer in axial flow compressors is discussed in this paper, and a new method for computing the blockage and the work lost coefficient suitable for engineering design and analysis of axial compressors is proposed. The off design performance analysis of two multistage axial flow compressors agrees well with the experimental results.
