Rotating Stall in Axial Flow Compressors
Journal of the Aeronautical Sciences, 1957The classical theories of linearized aerodynamics yields a complete description of the flow field due to the rotating stall in a two-dimensional cascade of airfoils, when the extension of the stalled region is small. The corresponding physical scheme can be used for larger stalled regions, without the limitations of the linearizing assumptions, if no ...

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.

Prestall Instability in Axial Flow Compressors
Journal of Turbomachinery, 2020Abstract The aim of the present paper is to improve the physical understanding of discrete prestall flow disturbances developing in the tip area of the compressor rotor. For this purpose, a complementary instrumentation was used in a single-stage axial compressor.

Circumferential Asymmetry in Axial Flow Compressors
The Journal of the Royal Aeronautical Society, 1966In this paper we are restricting our attention to those cases of circumferential inlet distortion where the distortion of the velocity profile is too large to be described as a small perturbation. Thus any theory describing the flow must use a mathematical model which is non-linear.

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 ...

Instrumentation for Axial-Flow-Compressor Research
Journal of Fluids Engineering, 1952Abstract A discussion of many of the air-flow instruments currently used in compressor research is given. A history of the development of some of the instruments is presented together with the reasons for adopting the present designs.

Observer Design for Axial Flow Compressor
Journal of Dynamic Systems, Measurement, and Control, 2014Flow disturbance is the main cause which leads to the instability occurred in aero-engines, and it is an infinite-dimensional quantity that is impossible for a direct online measurement in reality. The unstable flow not only results in a drastic pressure reduction but also can damage to engine's components during the compressor operations.

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.

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 1999
The purpose of this paper is to set out some of the basic principles and rules associated with the design of axial flow compressors, principally for aero-engines, as well as the practical constraints that are inevitably present. The thrust is primarily on the aerodynamic design but this cannot be divorced from the mechanical aspects and so some of ...

Preliminary Design of Axial Flow Compressors
2020With reference to an axial compressor stage, a procedure for the calculation of kinematic parameters at mean diameter (Sect. 4.1), thermodynamic parameters (Sect. 4.2), geometric parameters (Sect. 4.3), parameters in the radial direction (Sect. 4.4) and stage losses (Sect. 4.5) is provided. Then, Sect.
