Vortex reducer
Abstract:
The present disclosure relates to a vortex reducer (100) for a bleed flow (104) in an axial turbomachine comprising a rotor disc (113). The vortex reducer may comprise one or more guide channels (122) arrangeable adjacent to a first side (113a) of the rotor disc to at least partially de-swirl the bleed flow. The vortex reducer may further comprise a passage (130) connecting the first side of the rotor disc to a high pressure flow source capable of providing flow (134) to the first side of the rotor disc to mix with the bleed flow on the first side of the rotor disc.
