Pressure fluctuations due to ‘trapped waves’ in the initial region of compressible jets
Autor: Amy F. Fagan, P. Upadhyay, Khairul Zaman
Publikováno v: Journal of Fluid Mechanics. 931
An experimental study is conducted on unsteady pressure fluctuations occurring near the nozzle exit and just outside the shear layer of compressible jets. These fluctuations are related to ‘trapped waves’ within the jet's potential core, as inves

Experimental and computational study of tones occurring with a coaxial nozzle
Autor: Amy F. Fagan, Ivana Milanovic, Christopher J. Miller, Khairul Q. Zaman
Publikováno v: International Journal of Aeroacoustics. 18:189-206
The source of audible tones occurring with a coaxial nozzle is explored experimentally as well as computationally. The hardware is comprised of an inner and an outer nozzle, without a center-body, that are held together by a set of four struts. With

An investigation of a mixer-ejector nozzle for jet noise reduction
Autor: James Bridges, Khairul Q. Zaman, Amy F. Fagan, Raymond S. Castner
Publikováno v: 25th AIAA/CEAS Aeroacoustics Conference.
An experimental study is conducted assessing the performance of an ejector together with an 8:1 aspect ratio rectangular nozzle with the eventual goal of noise reduction for jet engines. Wall static pressure and Pitot probe surveys are conducted to e

Experimental Investigation of a One-sided Ejector Nozzle
Autor: Amy F. Fagan, James Bridges, Khairul Q. Zaman
Publikováno v: AIAA Scitech 2019 Forum.
A fundamental exploratory experiment is conducted assessing the performance of a one-sided ejector with the eventual goal of noise reduction for jet engines. The hardware is comprised of an 8:1 rectangular nozzle together with an ejector box whose lo

Variation of shock-spacing during screech stage-jumps
Autor: Michelle M. Clem, K. B. M. Q. Zaman, Amy F. Fagan
Publikováno v: International Journal of Aeroacoustics. 15:324-335
Flow visualization is used to investigate shock-spacings in a supersonic jet during stage-jumps associated with the screech phenomenon. Conventional schlieren and shadowgraphy techniques as well as a new projection focusing schlieren technique are em
