Turbo compressor or pump with fluid injection to influence the boundary layer

摘要

The flow driven machine has a rotor (6) with several rotor vanes (8) attached to a rotating shaft and a housing (1) for the flowing medium. The means for supplying fluid medium to at least one vane of one row are arranged at aerodynamically critical spots on the surfaces close to the edge and lower edges. - At least one stator (7) is provided which has fixed stator vanes (9). The fluid supply means have openings arranged axially symmetrical if they lie outside of the limits of the vane area.
