ABSTRACT:
A collector for a vaned diffuser in a centrifugal compressor, wherein the radial cross-sectional area of the collector housing at the entrance to the collector outlet duct is 40% to 80% of the entrance area of the outlet duct and progresses smoothly to the outlet duct entrance area. Progression in collector housing cross-sectional area is produced by variation of the collector axial height. At the intersection with the outlet duct, the collector has a step in axial height so as to at least partially direct circumferential flow from the collector into the outlet duct entrance.
