Chief Technology Officer Mark Anderson discusses a novel approach to extend compressor range through a passive method that prompts recirculation at low flow rates and corresponding higher back pressures. This recirculation method effectively establishes a higher local flow condition seen by the impeller and provides a stabilizing effect delaying the onset of stall . Various vane configurations and layouts in the secondary region are explained, and advantages and disadvantages of each are covered. The range extensions made possible by this method and the corresponding impact on performance is discussed.
