Abstract: In order to make clear the unstable flow phenomena observed at small flow rates in a centrifugal blower with inducer blades and radial blades, wall pressure fluctuation was measured by means of semiconductor pressure transducers installed at several points along the shroud casing wall. The frequency power spectrum and the auto-correlation coefficient of the pressure fluctuation measured at the inducer tip throat were analyzed to characterize the inception of unstable flow due to inducer stall. The focus was placed on the disturbances of wavelength larger than blade spacing for detecting the precursor of surge phenomenon.
