Abstract
A mathematical model is developed to analyze the suppression of rotating stall in a low speed centrifugal compressor, thereby addressing the important need for centrifugal compressor rotating stall and surge control. In this model, the precursor to instability is a weak rotating potential velocity perturbation that eventually develops into a (mite disturbance. To suppress the growth of this potential disturbance, a rotating control vortical velocity disturbance is introduced into the impeller inlet flow. The effectiveness of this control is analyzed by matching the perturbation pressure in the compressor inlet and exit flow fields with a model for the unsteady behavior of the compressor. The model predicts that favorable extensions of the compressor operating range are possible with such a control system.
