The present disclosure relates to shroud bleed in centrifugal compressors. An air-limiting component 130 may be located adjacent to a shroud 120. The shroud 120 may have a primary bleed slot 210, and the air-limiting component 130 may have a secondary bleed slot 310. The primary bleed slot 210 and the secondary bleed slot 310 may overlap at an effective bleed slot location. The air-limiting component 130 may rotate relative to the shroud 120, which may change a streamwise location of the effective bleed slot.
1. A centrifugal compressor comprising: a shroud located adjacent to an impeller, the shroud comprising a plurality of primary bleed slots;an air-limiting component located adjacent to the shroud, the air-limiting component comprising a plurality of secondary bleed slots overlapping the plurality of primary bleed slots, wherein the plurality of secondary bleed slots are offset by an angle from the plurality of primary bleed slots;a plurality of bearings located between the shroud and the air-limiting component; andan actuator configured to rotate the air...
