Numerical investigation of steady air injection flow to control rotating stall in centrifugal compressors حسب Halawa, Taher

"…Results also indicated that by using air injection, the number of stalled diffuser passages is decreased compared to the case of no injection. The most significant result of this paper is that using an angle of injection around twice the value of the diffuser vane angle gives the best results and makes the ideal correction of the fluid kinetic energy and fluid angle at the diffuser inlet. …"
