Zusammenfassung:A compressor of a turbine engine, the compressor including stator blades with shrouds, the shrouds being surrounded, at least in part, by rotating structure and forming a shroud cavity therebetween, the compressor including: a plurality of tangential flow inducers disposed within the shroud cavity; wherein each tangential flow inducer comprises a surface disposed on the rotating structure that is configured such that, when rotated, induces a tangential directional component to and/or increases the velocity of a flow of leakage exiting the shroud cavity.
