The only additional material here over that in chapter 4 is that it is convenient in the velocity diagrams to specify angles δ and γ for trigonometric purposes and polytropic stage efficiency is of importance since axial compressors, which are usually multistage machines are mostly designed on the basis of one stage with an assumed constant stage ...

Rotating stall in axial compressors
Zeitschrift für angewandte Mathematik und Physik ZAMP, 1955The phenomenon known as ‘rotating stall’ is described. Basically, it involves a nonuniform pattern of flow, steadily rotating relative to both the fixed and the rotating blades of axial-flow compressors. Attempts to analyze the phenomenon by means of small-perturbation theories are reviewed.

Axial-Centrifugal Compressor Program
1975Abstract : This report presents the component test results and analysis for Phases 3, 4 and 5 of the 5-lb/sec axial-centrifugal compressor. Separate component tests were carried out to evaluate the two-stage axial compressor, the centrifugal compressor, and the combined axial-centrifugal compressor.

Stall Inception in Axial Flow Compressors
Journal of Turbomachinery, 1991Studies have been conducted on two laboratory test compressors to investigate the process leading to the formation of finite amplitude rotating stall cells. The measurements were obtained from circumferential arrays of hot wires and were spatially and temporarily analyzed to show that modal perturbations are not always present prior to stall, and when ...
