Abstract: The use of boundarylayeringesting, embedded propulsion systems can result in inlet flow distortions where the interaction of the boundarylayer vorticity and the inlet lip causes horseshoe vortex formation and the ingestion ...

Abstract: In compression systems, the stable operating range is limited by rotating stall and/or surge. Two distinct types of stall precursors can be observed prior to full scale instability: the development of longwavelength modal ...

Abstract: One of the major challenges in highspeed fan stages used in compact, embedded propulsion systems is inlet distortion noise. A bodyforcebased approach for the prediction of multiplepuretone (MPT) noise was previously ...

Abstract: Highpressure multistage pumps and their coupled piping systems, typically used in the process and power generation industry, can experience dangerous systemlevel instabilities. This can occur at flow coefficients well away ...

Abstract: This paper presents a comprehensive assessment of real gas effects on the performance and matching of centrifugal compressors operating in supercritical CO2. The analytical framework combines first principles based modeling ...

Abstract: As the propulsor fan pressure ratio (FPR) is decreased for improved fuel burn, reduced emissions and noise, the fan diameter grows and innovative nacelle concepts with short inlets are required to reduce their weight and ...
