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 ...
