Active Control of Rotating Stall in Axial Compressors
We start from the dynamic equations of the comprimating systems (Greitzer-1976) and we make a nondimensionalizing the mass flow rate, the pressure and the time to obtain the nondimensional governing equations. To analyse the stability we apply the Routh Hourwitz criterion and we determin the useful stability range for compressor stability. We propose an interesting concept of dynamic stabilizat...

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...
متن کاملNumerical Investigation of Rotating-Stall in a Stage of an Axial Compressor with Two Different Approaches
An unsteady two-dimensional finite-volume solver was developed based on Van Leer’s flux splitting algorithm in conjunction with “Monotonic Upstream Scheme for Conservation Laws (MUSCL)” limiters and the two-layer Baldwin-Lomax turbulence model was also implemented. To validate the solver, two test cases were prepared and the computed results had good agreements with reference data. The rotating...
