Redesign of an Industrial Compressor Stage


Design Targets
Redesign a state-of-the-art industrial compressor stage, consisting of impeller, diffuser and de-swirl vane to improve stage efficiency while improving a stable operating range.

Geometry of the impeller, diffuser and de-swirl vane.

The stage efficiency was improved by up to 5 points with improvement in stable operating range.
