Abstract
The present disclosure relates to shroud bleed in centrifugal compressors. An air-limiting componentmay be located adjacent to a shroud. The shroudmay have a primary bleed slot, and the air-limiting componentmay have a secondary bleed slot. The primary bleed slotand the secondary bleed slotmay overlap at an effective bleed slot location. The air-limiting componentmay rotate relative to the shroud, which may change a streamwise location of the effective bleed slot.
