Rotating Stall in Axial Flow Compressors
Ever increasing demand of higher pressure ratio of aero-engine compressors has always been hindered by two distinct aerodynamic instabilities. The first known as surge is; large one dimensional periodic mass flow fluctuation through the compressor, which involves the entire pumping system including compressor, ducting, plenum and throttle. The second is the rotating stall which can be character...

متن کاملLocal Nonlinear Control of Stall Inception in Axial Flow Compressors
A combination of theoretical and computational nonlinear analysis techniques are used to study the scenario of bifurcations responsible for the initiation of rotating stall in an axial ow compressor model. It is found that viscosity tends to damp higher-frequency modes and so results in a sequence of bifurcations along the uniform-ow solution branch to stall cells of diierent mode number. Lower...
متن کاملStability Analysis for Rotating Stall Dynamics in Axial Flow Compressors*
This paper analyzes the nonlinear phenomenon of rotating stall via the methods of projection [Elementary Stability and Bifurcation Theory, G. Iooss and D. D. Joseph, Springer-Verlag, 1980] and Lyapunov [J.-H. Fu, Math. Control Signal Systems, 7, 255278, 1994]. A compressor model of Moore and Greitzer is adopted in which rotating stall dynamics are associated with Hopf bifurcations. Local stabil...
متن کاملRotating stall control for axial #ow compressors
Rotating stall is a primary constraint for the performance of axial #ow compressors. This paper establishes a necessary and su$cient condition for a feedback controller to locally stabilize the critical equilibrium of the uniform #ow at the inception of rotating stall. The explicit condition obtained in this paper provides an e!ective synthesis tool for rotating stall control. 2001 Elsevier Sci...
