| Abstract: | 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. |
