Effects of " suction ring" and "separator", which are used to improve the off-design operations of axial-flow compressors, on the performance curves and stall conditions are studied experimentally. A suction ring has a large effect on the rotating stall characteristics. Application of suction ring with unsuitable geometrical dimensions results in undesirable rotating stall, and the decrease in discharge pressure becomes more remarkable than that of one with out suction ring. On the other hand, a separator has quite useful improving effects on the rotors in which rotating stall occurs. The most effective geometrical dimensions are shown in consideration of partial flow rate performance, stall condition and noise. In addition, the working mechanism of the separator is discussed.
