Abstract: “Tworegimesurgeâ€‌ is a special instability behavior of compressors, which was investigated in this paper. When the compressor operates at medium rotor speed, mild surge happens first, where the transient pressure signals ...

Abstract: Variable inlet prewhirl is an effective way to suppress compressor flow instability. Compressors usually employ a high degree of positive inlet prewhirl to shift the surge line in the performance map to a lower mass flow ...

Abstract: Abstract. This study employs high-fidelity, unsteady, three-dimensional computational fluid dynamics (CFD) simulations to develop a comprehensive framework for engine-airframe integration, investigating the aerodynamic ...
