N2 - An analysis is presented of the dynamics of a representative axial flow compressor model, emphasizing the influence of two important control parameters. These are a nondimensional parameter, B, as a primary determinant of poststall behavior and the setting of the throttle line. E. M. Greitzer's lumped-parameter model (1976) is employed in this study, with a specific choice of compressor and throttle characteristics. The analysis shows the presence of a rich variety of global as well as local bifurcations as the two control parameters are varied. The analysis leads to a characterization of compressor operation into three major zones: the stalled zone, the prestall zone, and the normal (unstalled) zone. Simulation results demonstrate the qualitatively different dynamical behaviors within each regime of parameter space.
