On Steady Solutions of a PDE Model of Compressor Stall

Research output: Contribution to journalConference articlepeer-review


We analyze stability properties of steady state solutions of a simplified reaction-diffusion model and the Moore-Greitzer model of axial compressor stall. Steady state solutions are expressed as critical points of an energy function and are computed by continuation and bifurcation methods. For both the reaction-diffusion and Moore-Greitzer models, it is shown that the solutions asymptotically approach these critical points. We obtain multiple unstable solutions and discuss their relevance to nonlinear stall inception and control.
