Prestall Instability in Axial Flow Compressors

Journal of Turbomachinery, 2020
Abstract 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.

Rotating Stall in Axial Flow Compressors

Journal of the Aeronautical Sciences, 1957
The 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 ...

Circumferential Asymmetry in Axial Flow Compressors

The Journal of the Royal Aeronautical Society, 1966
In 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.

Stall Inception in Axial Flow Compressors

Journal of Turbomachinery, 1991
Studies 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 ...

Observer Design for Axial Flow Compressor

Journal of Dynamic Systems, Measurement, and Control, 2014
Flow 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.

Maximum loading capability of axial flow compressors [PDF]

Journal of Aircraft, 1983
A maximum loading prediction system for determining the design speed stall margin capability of axial flow compressors is presented The formulation of the primary correlations for this system is based on the analogy between a compressor cascade and a diffuser passage Semiempirical corrections are applied to relate the initial cascade derived maximum ...

Axial-Flow Compressors and Ducted Fans

2010
Publisher Summary This chapter presents the basic characteristics of axial-flow compressors and ducted fans. It also covers the analysis of axial-flow compressors stage (mean-line analysis, velocity diagrams, thermodynamics, and stage loss relationships and efficiency) and axial-flow compressors rotors.
