A fluid flow machine includes an annulus duct formed between a casing and a rotor drum, which is rotatable about a machine axis. At least one row of rotor blades is arranged in the annulus duct, with the latter forming a main flow path and with at least one fluid injector nozzle being arranged in the area of a wall of the casing and/or of the rotor drum. At least part of the injector nozzle protrudes into the main flow path and is provided for the generation of a jet which is tangentially directed to the wall of the main flow path. |
