Abstract

To study the effect of Greitzer B parameter and throttle parameter γ on post-stall behavior of axial flow compressor

the static bifurcation behavior for post-stall of axial flow compressor was analyzed using bifurcation analysis method.In the γ-B bifurcation parameter space

the sketch map for steady and unsteady flow of compressor was plotted out.It is thus concluded that nonlinear bifurcation analysis can accurately capture typical post-stall transients and easily analyze the change of stability of system equilibriums under bifurcation parameters.
