Screech Tones from Rectangular Jets with Spanwise Oblique Shock-cell Structures
(Cambridge Univ Press, 1997-01-10)
Understanding screech is especially important for the design of advanced aircraft because screech can cause sonic fatigue failure of aircraft structures. Although the connection between shock-cell spacing and screech ...
Resonant interaction of a linear array of supersonic rectangular jets: An experimental study
(CAMBRIDGE UNIV PRESS, 1996-02-25)
This paper examines a supersonic multi-jet interaction problem that we believe is likely to be important for mixing enhancement and noise reduction in supersonic mixer-ejector nozzles. We demonstrate that it is possible ...
INSTABILITY MODES EXCITED BY NATURAL SCREECH TONES IN A SUPERSONIC RECTANGULAR JET
(AMER INST PHYSICS, 1994-12)
Cessation of Screech in Underexpanded Jets
(Cambridge Univ Press, 1997-04-10)
In significantly underexpanded jets, screech inherently ceases to exist. This paper studies screech cessation in a supersonic rectangular jet and provides an explanation for its occurrence. Experimental data are presented ...
Supersonic Jet Screech: Half-century from Powell to the Present
(Academic Press Ltd, 1995-08-19)
Under certain conditions, shock-containing jets produce an intense tone referred to as screech. Screech was discovered about half a century ago by Alan Powell in England. Here I recount developments in supersonic jet screech ...
Aeroacoustic Characteristics of a Rectangular Multi-element Supersonic Jet Mixer-ejector Nozzle
(Academic Press Ltd, 1997-10-23)
This paper provides a unique, detailed evaluation of the acoustics and aerodynamics of a rectangular multi-element supersonic jet mixer-ejector noise suppressor. The performance of such mixer-ejectors is important in ...
Advances in Understanding Supersonic Jet Screech: Review and Perspective
(Pergamon - Elsevier Science Ltd, 1998-02)
Screech tones are produced by imperfectly expanded jets under certain conditions. This paper provides an overview of developments in the field of supersonic jet screech. The overview includes a historical background, summary ...
