Vortex reducer

摘要

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.

1. A vortex reducer for a bleed flow in an axial turbomachine comprising a rotor disc, the vortex reducer comprising:
one or more guide channels arrangeable adjacent to a first side of the rotor disc to at least partially de-swirl the bleed flow; a passage connectable to a high pressure flow source, the passage being adapted to provide a secondary flow from the high pressure flow source to mix with the bleed flow on the first side of the rotor disc, wherein the one or more guide channels are each defined by one or more guide portions adapted to guide and at least partially de-swirl the bleed flow, and an outlet of the passage is provided in a further channel provided within the guide portions.
