The axial flow compressor is the second type of dynamic compressor, whose general nature and capabilities were introduced in section 1.3. It absorbs energy from an external power source, raising the pressure of a continuous flow of working fluid by means of its blading geometry and motion.

Investigations of Axial-Flow Compressors
Journal of Fluids Engineering, 1951Abstract An approximate theory of the general perfect fluid flow in axial turbomachines is presented. The validity of the simplifying assumptions of the theory is justified by comparison with flow patterns measured in a large, low-speed, axial-flow compressor.

Axial Compressors and Turbines
2012With the definition of the work coefficient in (6.4a) and (6.4b), we can now write from (4.22a) to (4.22d) the nondimensional azimuthal velocity component expressions as follows: $$ \frac{{{{c}_{\rm{u1}}}}}{u} = \left( {1 - \hat{r}} \right) - \frac{\Psi}{4} $$ $$ \frac{{{{c}_{\rm{u2}}}}}{u} = \left( {1 - \hat{r}} \right) + \frac{\Psi}{4} $$

Review—Axial Compressor Stall Phenomena
Journal of Fluids Engineering, 1980Stall in compressors can be associated with the initiation of several types of fluid dynamic instabilities. These instabilities and the different phenomena, surge and rotating stall, which result from them, are discussed in this paper. Assessment is made of the various methods of predicting the onset of compressor and/or compression system instability,

Centrifugal and Axial Compressors
2016This chapter and Chap. 10 treat the rotating modules of both aero engines and gas turbines. These modules are compressible turboachinery (or turbomachines). Let us first introduce a definition for turbomachines. The word (turbo) or (turbines) is of Latin origin, meaning “that which spins or whirls around.” Though compressible turbomachines may be fans,

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.
