Crossover Systems Between the Stages of Centrifugal Compressors

Abstract

The location and orientation of vanes in an annulus are established on the basis of two principles which result from a discussion of simple elbows. These principles are incorporated into a procedure for designing the diffuser vanes in the crossover passage between stages of a centrifugal compressor. To test the proposed design a low-speed model was built and tested and the results compared with a second model which represented a more conventional design.
