ABSTRACT:
The effective efficiency of a centrifugal compressor can be improved by achieving a uniform distribution of fluid velocity across the outlet end of a fluid passage of an axial diffuser for the centrifugal compressor and a high static pressure recovery ratio Cp in the axial diffuser passage. The cross section of each axial diffuser passage is configured such that a relatively high velocity fluid flow in an upstream part of the diffuser passage is directed toward a negative pressure side of a cross section thereof. It can be accomplished by directing a minor axis of a cross section of the diffuser passage substantially perpendicularly to a direction directed from a center of the cross section of the diffuser passage to the central axial line of an impeller or directing the minor axis toward the central axial line of the impeller.
