Experimental investigation of the tip leakage flow in a low-speed multistage axial compressor. [PDF]
Sci Prog, 2020 Casing pressure measurements and Stereoscopic Particle-Image Velocimetry (SPIV) measurements are used together to characterize the behavior of the rotor tip leakage flow at both the design and near-stall conditions in a low-speed multistage axial ...

Non-Uniform Flow in Multistage Axial Compressors. [PDF]
, 1977 It has been suggested by the author that some aspects of severely distorted flow into multistage compressors may be examined utilizing an integral technique. The general idea of the proposed technique is clear enough; the appropriate equations of motion and energy are integrated peripherally and radially, using reasonable assumptions for the ...

The New Performance Calculation Method of Fouled Axial Flow Compressor [PDF]
The Scientific World Journal, 2014 Fouling is the most important performance degradation factor, so it is necessary to accurately predict the effect of fouling on engine performance. In the previous research, it is very difficult to accurately model the fouled axial flow compressor.

Noise Reduction Studies for a Multistage Axial Flow Transonic Compressor [PDF]
The Journal of the Acoustical Society of America, 1967 It is the purpose of this paper to describe an aircraft-type transonic compressor built especially for noise research studies and to present some preliminary results. This compressor is unique in that it is adjustable over a very wide range of operating conditions.

Stability of Flow Through Multistage Axial Compressors [PDF]
Volume 1: Turbomachinery, 1989 This paper describes measurements of the performance of a research stage operating in isolation and as part of a multistage compressor. It is shown that the stall point and the stalled performance of the stage are properties of the system in which it operates rather than a property of the stage itself. The consequences of this for the estimation of the

Aerodynamic analysis of a high-loaded multistage axial compressor at design conditions [PDF]
Scientia Sinica Technologica, 2020 Transonic compressors are an important approach for meeting the requirement of high-loaded compressors in state-of-the-art gas turbines. Such compressors increase the average pressure ratio per stage but cause complicated flow structures introduced by ...
