Experiment of self-recirculation tip injection in low speed single-stage compressor

  • Experiment of self-recirculation tip injection was performed.The effect of different air-entraining ways on the stall margin improvement (SMI) and efficiency were analyzed.The mechanism of stability range extension was also discussed.It is demonstrated that the self-recirculation tip injection can enhance the stall margin effectively,and can also increase the peak efficiency appreciably.Compared with the tip injection with external air source,the proposed method can save the auxiliary equipment which supplies the external air.The self-recirculation tip injection is simple and practical,and is of great value in many applications.
