A stall diagnosis method based on entropy feature identification in axial compressors
International Journal of Mechanical System Dynamics, 2023 A stall diagnosis method based on the entropy feature extraction algorithm is developed in axial compressors. The reliability of the proposed method is determined and a parametric sensitivity analysis is experimentally conducted for two different types ...

Effect of Non-Uniformity of Rotor Stagger Angle on the Stability of a Low-Speed Axial Compressor
Energies, 2022 It is well known that variations in stagger angle between rotor blades affect compressor performance. In this paper, the stagger angle of blade No. 8 is increased or decreased by six degrees for non-uniformity, and the influence of rotor non-uniformity ...

Origins and Structure of Spike-Type Rotating Stall [PDF]
, 2018 In this paper we describe the structures that produce a spiketype route to rotating stall and explain the physical mechanism for their formation. The descriptions and explanations are based on numerical simulations, complemented and corroborated by ...

Stall Inception and Development in an Axial Flow Aeroengine [PDF]
Journal of Turbomachinery, 1993 This paper describes the phenomenon of stall and surge in an axial flow aeroengine using fast response static pressure measurements from the compressor of a Rolls-Royce VIPER engine. It details the growth of flow instability at various speeds, from a small zone of stalled fluid involving only a few blades into the violent surge motion of the entire ...

Observations of the Growth and Decay of Stall Cells during Stall and Surge in an Axial Compressor
International Journal of Rotating Machinery, 2017 This research investigated unsteady events such as stall inception, stall-cell development, and surge. Stall is characterized by a decrease in overall pressure rise and nonaxisymmetric throughflow.
