Abstract
A crossover duct assembly for providing flow communication between multiple stages of centrifugal compressors and the like. The duct assembly includes inner and outer wall sections forming a continuous annular flow path between compressor stages for turning radially outward gas flow to a radially inward direction. The duct includes a thin vane diffuser section, a vaneless turning bend having an elongated wall geometry, and a deswirl vane section for enhancing smooth gas flow with minimum pressure loss.
