Conceptual Design of a Centrifugal Compressor Including Consideration of the Effect of Inlet Prewhirl
Keyword(s):
A non-dimensional impeller design procedure, including the effect of inlet prewhirl, is described. It is shown that the basic non-dimensional parameters commonly used to present the performance of compressors also provide an adequate basis from which a conceptual design procedure can be developed. The adoption of composite non-dimensional groupings such as specific speed and specific diameter are unnecessary. The design procedure is developed non-dimensionally to provide the appropriate impeller geometry as a ratio of the outer radius, and inlet and discharge blade angles. A compressor design for a pressure ratio of 4 to 1 is used to provide an illustrative example.
