Aerodynamic Development of Stages for Industrial Centrifugal Compressors: Part 2 — Test Data Analysis, Correlation and Use

The considerable amount of experimental data collected on specifically designed single-stage test rigs are correlated so as to allow a straightforward use for the design and performance prediction of stage configurations needed for industrial compressor manufacture. Internal stage flow-field measurements are further analyzed by means of proper methods to achieve information valid for improving existing stage, fluid-dynamic models. Suitable use of the stage performance data allows the laying out of standard stage series of given geometries capable of satisfying a wide range of requirements without continuously resorting to specific, restricted application designs.
