ABSTRACT:
A turbomachine has at least one stator (4) and at least one downstream rotor (7), with the stator (4) being provided with stationary stator blades and the rotor (7) comprising several rotor blades attached to a rotating shaft. A casing (2) confines the passage of fluid through the rotor (7) and the stator (4) in the outward direction. A mechanism for peripheral jet creation is provided in the area of at least one vane of the stator (4), with at least one nozzle (21) issuing fluid at the radially outer boundary of a main flow path.
