Modeling and control for axial ow compression systems have received great attention in recent years. The objectives are to suppress rotating stall and surge, to extend the stable operating range of the compressor system, and to enlarge domains of attraction of stable equilibria using feedback control methods. The success of this research eld will signiicantly improve compressor performance and ...

One of the possible origins of High Cycle Fatigue in a compressor blade is the rotating stall under the influence of (rotating) inlet pressure or temperature distortion leading to a varying angle of attack on the compressor blades. This paper will be oriented towards the propagation of total pressure and total temperature nonuniformities in axial flow fans and compressors and their subsequent e...

Despite the generally accepted notion that geometric variability is undesirable in turbomachinery airfoils, little is known in detail about its impact on aerothermal compressor performance. In this work, statistical and probabilistic techniques were used to assess the impact of geometric and operating condition uncertainty on axial compressor performance. High-fidelity models of geometric varia...

Abstract As the next generation of turbomachinery components becomes more sensitive to instrumentation intrusiveness, a reduction number measurement devices required for evaluation performance is possible and cost-effective way mitigate arising non-mastered experimental errors. A hybrid methodology that couples techniques with modeling through Bayesian data-driven framework employed reduce effo...

The onset of rotating stall and surge in compressors limits the operating range aero-engines. Accurately predicting key features during these events is critical engine design process. In this paper, a three-dimensional computational model for transient simulation multi-stage axial proposed. kinetic equations describing dynamic process compression system are constructed, with 3D through-flow par...
