RISThe Tip Clearance Flow Resonance Behind Axial Compressor Nonsynchronous Vibration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonsynchronous vibration (NSV) is a particular type of aero-elastic phenomenon, where the rotor blades vibrate at nonintegral multiples of the shaft rotational frequencies. NSV behavior appears ...
Blade Tip Clearance Flow and Compressor Nonsynchronous Vibrations: The Jet Core Feedback Theory as the Coupling Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the role of tip clearance flow in the occurrence of nonsynchronous vibrations (NSVs) observed in the first axial rotor of a high-speed high-pressure compressor in an ...
