Numerical Study on End Wall Synthetic Jet to Improve Performance and Stability Margin of a High-speed Subsonic Axial Compressor Rotor [PDF]

Journal of Applied Fluid Mechanics, 2023
Synthetic jet has been confirmed as a novel flow control technology. However, the existing application research on synthetic jet in axial flow compressor is still confined to cascade or low-speed axial flow compressors, and rarely high-speed axial flow ...
