| Abstract: | Several stages of a multistage axial compressor have been investigated to study the effect of inter-stage bleeding on compressor total performance and local flow field.According to the requirement of the maximum bleed flow rate,three different configurations of bleeding slot(rectangular slot,circular slot and odd slot) were presented.Numerical simulations of the flow field were conducted.The results show that,the rectangular slot and circular slot designed here almost have the same effect on compressor tota... |
