On supersonic combustion

Science in China Series A: Mathematics, 1999
Some basic concepts and features of supersonic combustion are explained from the view point of macroscopic aerodynamics. Two kinds of interpretations of supersonic combustion are proposed. The difference between supersonic combustion and subsonic combustion is discussed, and the mechanism of supersonic combustion propagation and the limitation of heat ...

Supersonic Combustion: Modelling and Simulations

14th AIAA/AHI Space Planes and Hypersonic Systems and Technologies Conference, 2006
Mixing and combustion of supersonic reacting flows are currently under investigation for new generation launchers and trans-atmospheric vehicles. Experimental results with hydrogen injected at Mach 2.5 in a Mach 2 airstreams showed combustion taking place just in ∼0.6 m: this indicates that supersonic combustion is very efficient.

Physics and Regimes of Supersonic Combustion

AIAA Journal, 2010
Understanding the physics of supersonic combustion is the key to design a performing engine for scramjet-powered vehicles. Despite studies on supersonic combustion dating back to the 1950s, there are still numerous uncertainties and misunderstandings on this topic.

Mixing and Combustion in Supersonic Reactive Flows

44th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2008
Supersonic combustion is a key issue in any future plan to develop supersonic combustion (SC) ramjets (SCRJ) and rocket based combined cycles (RBCC) vehicles. Past experience has shown that among the major fundamental problems to be solved in SC are the need for rapid (i.e., < 1 ms) mixing and combustion efficiency.

LES of supersonic combustion in a scramjet engine model

Proceedings of the Combustion Institute, 2007
In this study, Large Eddy Simulation (LES) has been used to examine supersonic flow and combustion in a model scramjet combustor. The LES model is based on an unstructured finite volume discretization, using total variational diminishing flux ...

Reaction Regimes in Supersonic Combustion

47th AIAA Aerospace Sciences Meeting including The New Horizons Forum and Aerospace Exposition, 2009
Large-eddy simulations (LES) of supersonic combustion are considered to be an important tool to better understand the physics of supersonic reactive flows. To correctly predict the flame anchoring and the flame structure, the implementation of a appropriate SGS scale model is crucial, and its physics and derivation are analyzed in the present work.

Combustion in supersonic flow

Combustion, Explosion and Shock Waves, 1987
Examples of numeric modeling of complex combustion processes in supersonic flows are presented which illustrate the possibility of obtaining useful information which may reveal their basic regularities determined by the parameters of the entrance streams, mode of injection, type of fuel, and the interaction of various factors pertaining to combustion ...
