The performance prediction of axial flow compressors at different speeds and under various pressure ratio conditions are still being developed because of costly empirical experiments. One-dimensional modeling is a simple, fast and accurate method for performance prediction in any type of compressor with different geometries. In this approach, inlet flow conditions and compressor geometry are kn...

Local output feedback stabilization with smooth nonlinear controllers is studied for parameterized nonlinear systems of which the linearized system possesses multiple pairs of imaginary eigen-values, and the bifurcated solution is unstable at the critical value of the parameter. Necessary and suucient conditions are sought for stabilization of such nonlinear bifurcated systems based on the proj...

♦ Corresponding Author, Chief Technology Officer: [email protected] ABSTRACT Ramgen Power Systems, Inc. (RPS) is developing a family of high performance supersonic compressors that combine many of the aspects of shock compression systems commonly used in supersonic flight inlets with turbo-machinery design practices employed in conventional axial and centrifugal compressor design. The result i...

surge and rotating stall phenomena are two dynamic instabilities that occur in both axial and centrifugal compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressing surge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. this resear...

Control and Modeling for stall and surge phenomenon in axial flow compressors have received great importance in recent times. In power generation plant and aerospace propulsion compression system are prone to the aerodynamic instabilities of stall and surge. In aero engine compressors higher pressure ratio has always been a growing stipulates which has over involved by diverse rotating stall an...

Rotating blade and disk fatigue failures cause a fairly small percentage of machine shutdowns, but can require extensive repairs and downtime. This tutorial focuses on steam turbines, centrifugal compressors, and axial compressors primarily for refineries and process plants. For steam turbines, axial compressors, and openimpeller centrifugal compressors, the main concern is resonance giving bla...
