Range Vs. Efficiency—Striking The Proper Balance
MetadataShow full item record
The paper addresses the balance between peak attainable efficiency and overall operating range that must be addressed when specifying, designing and/or selecting centrifugal compressors. The relative roles of the various compressor components; i.e., impellers, diffusers, guide vanes, and return channels; in achieving the proper balance are discussed. Finally, the importance of proper component and stage aerodynamic matching is emphasized.
