Abstract

Detailed measurements using hot-wire anemometery and high frequency Kulite transducer at centrifugal impeller outlet reveal a complex nature of flow behavior across blade to blade pitch. The impeller outlet flow has two distinct regions called jet and wake. These regions are identified by measuring the variations of flow velocity, angle and pressure. The impeller outlet flow is characterized by defining certain non-dimensional parameters and correlating them with flow coefficient which are useful in the design of centrifugal impellers
