Talk:Compressor characteristic

Untitled
I disagree that compressors maps are usually presented in dimensionless co-ordinates. IMO, actual volumetric flow vs polytropic head remains the industry standard.

The Buckingham Pi method might be mathematically elegant but it rarely captures the actual movement of compressor curves when the gas molecular weight changes. This is borne out by analysis of actual compressor performance data. I'd like to see some further evidence of the effectiveness of the dimensionless approach before claiming it as the preferred or standard approach.

ME TOO. The usual and convenient form of presenting dynamic compressor performance is with Actual Volumetric Flow vs Head.

The whole article need re-writing, as it fails to properly describe the differences among the very different geometries of Centrifugal and Axial compressors, so Surge phenomena is badly described. Surge is a complex phenomena, and its control is necessarily a complex subject, that the article misses almost entirely.
