Abstract

A multiple stage centrifugal compressor has baffle rings attached at the inlet to each of the impellers, between a shroud side curvature and a hub side curvature.
The dimensions and spacings of the baffle rings are selected as a function of the shroud side radius of curvature R S and the hub side radius of curvature R H. For two baffle rings, the radii are R C1 = (R C2 x R H)1/3 and R C2 = (R S x R H2)1/3.
