Centrifugal compressor and multiple stages.

摘要

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 RS and the hub side radius of curvature RH. For two baffle rings, the radii are RC1=(Rc2xRH)1/3and RC2=(RSxRH2)1/3.
