ABSTRACT:
A flow control system for a centrifugal compressor includes a plurality of suction holes provided in a diffuser and configured to facilitate suction of a flow control stream from a boundary layer fluid from the diffuser. A plurality of blowing holes are provided in a first interconnecting duct coupled to a de-swirl vane unit and configured to facilitate blowing of the flow control stream into the first interconnecting duct. The blowing holes may also be provided in a suction side or an end wall side of the de-swirl vane unit or in a second interconnecting duct coupled between the de-swirl vane unit and an impeller or an upstream diffuser of another compression stage. A manifold is coupled between the suction holes and the blowing holes and configured to direct flow of the flow control stream from the suction holes to the blowing holes.
