Time-Frequency Characterization of Rotating Instabilities in a Centrifugal Pump with a Vaned Diffuser

This paper presents acoustic and flowdynamic investigations of large-scale instabilities in a radial pump with a vaned diffuser. Pressure fluctuations were measured with transducers placed flush at the inlet duct, at the impeller discharge, and in the vane diffuser walls. Two impeller rotation speed...
