Abstract In the previous part of paper, a novel method to reconstruct compressor nonuniform circumferential flow field using spatially undersampled data points is developed. this applied two research articles further demonstrate potential in resolving important features associated with these nonuniformities. first experiment, static pressure at leading edge vaned diffuser high-speed centrifugal...

This thesis contains new results in the eld of modeling and control of rotating stall and surge in compressors. A close coupled valve is included in the Moore-Greitzer compression system model and controllers for both surge and rotating stall is derived using backstepping. Disturbances, constant and time varying, are then taken into account, and nonlinear controllers are derived. Stability resu...

this paper deals with aerodynamic design of fan and compressor assembly for turbofan engines having arbitrary by-pass ratios. two different softwares were developed in this respect. first, based on general performance data at design point condition, a one-dimensional approach was activated. initial flow passages of both fan and compressor, together with splitter position were developed utilizin...
