Aero-acoustic performance of a continuous transonic wind-tunnel axial-flow compressor

Xibei Gongye Daxue Xuebao, 2022
A three-stage axial-flow compressor was developed for a continuous transonic wind tunnel. The rotor-stator spacing and the ratio of number of rotor blades to number of stator vanes were properly chosen for the purpose of aero-acoustic noise suppression ...

Effect of Different Types of External Guide Vanes on the Performance of High-Pressure Centrifugal Compressor [PDF]

Journal of Applied Fluid Mechanics, 2023
In order to reduce exit swirl and obtain the desired Mach number, axial exit guide vanes (EGV) are often employed in a centrifugal compressor. NASA CC3 compressor, with wedge vane diffuser and without EGV, is considered as the base model for the analysis

Effect of Tip Gap Size on the Performance of an Axial Compressor Stage with and without Active Flow Control

International Journal of Turbomachinery, Propulsion and Power, 2023
The tip gap region of an axial compressor rotor is a source of complex flows, inducing losses and stability issues. Recent works have proven the ability of blowing high-speed jets in the tip region to improve the surge margin of an axial compressor stage
