Journal ArticleDOI
A review of active control of combustion instabilities
TL;DR: In this paper, the authors present a discussion of different methods which can be used to suppress combustion instabilities using active control, as well as a review of the work which has recently been performed in this area of combustion research.
Unsteady Motions in Combustion Chambers for Propulsion Systems
F. E. Culick,Paul Kuentzmann +1 more
TL;DR: The main mechanisms for combustion instabilities in liquid and solid fueled rockets, ramjets, thrust augmentors, and gas turbines are discussed in this paper, with a broad summary of the basic material required to understand the subject.
Journal ArticleDOI
Vortex-Shedding Phenomena in Solid Rocket Motors
TL;DR: In this article, the meanings of various Strouhal number definitions are discussed and the basic mechanisms for sound production in ducts or chambers are then discussed through simple tools, such as the linear hydrodynamic stability analysis, Flandro's method and the acoustic balance technique, which provide good insights into the physics of the phenomenon.
Journal ArticleDOI
Internal flow field studies in a simulated cylindrical port rocket chamber
TL;DR: In this article, the mean and fluctuating speed and turbulent shear stresses were measured in the principle coordinate directions using three-element hot-wire anemometers, showing that noticeable velocity fluctuations in the head end region generally decrease in intensity, relative to centerline speed, over the first five port diameters.
Journal ArticleDOI
Instabilities and pressure oscillations in solid rocket motors
Yves Fabignon,Joel Dupays,Gérard Avalon,Francois Vuillot,Nicolas Lupoglazoff,Grégoire Casalis,Michel Prévost +6 more
TL;DR: In this article, an overview of the main results obtained on instabilities and pressure oscillations in segmented solid rocket motors is given. But the most important recent result inside ASSM and POP programs was the discovery of the parietal vortex shedding and the role of aluminum combustion on the instabilities.

Interaction between sound and flow in acoustic cavities: mass, momentum, and energy considerations,
R. H. Cantrell,R. W. Hart +1 more
TL;DR: In this article, the authors investigated requirements for neutral acoustic stability in cavities with a transpiring wall where there is a mean flow in the absence of acoustic disturbances and the growth rates of the acoustic fields were also considered.
Journal ArticleDOI
Stability of Three-Dimensional Motions in a Combustion Chamber
TL;DR: In this paper, the influence of particulate matter and boundary processes on linearized three-dimensional motions in a non-uniform flowfield is re-examined, and the results are applied to a problem of linear stability in solid propellant rocket motors.
Journal ArticleDOI
Excitation of acoustic modes in a chamber by vortex shedding
Fred E. C. Culick,K. Magiawala +1 more
TL;DR: The interfaces of the grains are coated with inert, slow-burning material as discussed by the authors, and the inert material is exposed in the form of annular rings oriented normal to the axis of the chamber.

Vortex generated sound in cavities
Gary A. Flandro,H. Jacobs +1 more
TL;DR: In this paper, a simple model is examined which represents a feedback mechanism between the vortex shedding process and the acoustic modes produced by the vortices, and it is shown that the growth of acoustic waves is greatest when the characteristic frequency of vortex shedding is commensurate with a natural acoustic frequency of the cavity.

Some Experiments concerning the Hole and Ring Tone
R. C. Chanaud,Alan Powell +1 more
TL;DR: In this article, a flat plate perpendicular to the jet axis, there being a hole in the plate of the same diameter as the jet orifice and concentric with the jet, and a ring whose plane was perpendicular to a jet axis and whose diameter was equal to that of the orifice was observed.
