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 ...

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.

Spectral Simulation of Supersonic Reactive Flows

SIAM Journal on Numerical Analysis, 1998
The authors present a Chebyshev collocation scheme for the numerical simulation of reactive flows with shock waves. It is shown that spectral methods are suitable for the numerical approximation of reactive flows interacting with shock waves. Theoretical and numerical results on interactions of hydrogen jets with shock waves are analyzed, and ...

Linearized supersonic flow

1947
This thesis is a presentation of the methods and concepts of the theory of linearized supersonic flow. The fundamental theory which serves as a basis for this investigation is discussed in the first two chapters. Special emphasis is placed upon the study of planar systems. A system of conical coordinates is introduced in which the method of separation

Flow Dominating Instability in Supersonic Flows

2020
The shock-induced separation is a common phenomenon in supersonic combustion, especially when the scramjet combustor works under high equivalence ratios. The low-speed recirculation zone and strong heat release enable the separated region to be an ideal place for flame stabilization.

Supersonic gas flow

British Journal of Applied Physics, 1954
An introduction to supersonic gas flow is given, with emphasis on the features that distinguish supersonic from subsonic flow. Experimental methods for the study of supersonic flow are briefly considered and some simple flows are described.

A Computational Method for Combustion in Supersonic Flows

47th AIAA/ASME/SAE/ASEE Joint Propulsion Conference &amp; Exhibit, 2011
A numerical technique to solve two-dimensional reacting ow eld in chemical nonequilibrium is presented. The aim of this study is to develop a computational tool which permits the analysis of combustion phenomena at high speed ows. The numerical approach is based on a time-dependent, nite-volume integration of the Euler equations suitably modi ed for ...

Subsonic and Supersonic Flows

2010
Compressible flow past thin wings and slender bodies are studied. First, subsonic flow past thin wings are analyzed by means of potential flow theory. The kernel function method is introduced for arbitrary planforms undergoing simple harmonic oscillations.

Flow Field Study of a Supersonic Jet Exiting into a Supersonic Stream

2006
The paper present a numerical/experimental investigation of the flow field resulting around a generic vehiole controlled by means of a lateral jet in supersonic motion. The experimental data are acquired in the DLR wind tunnel TMK in Cologne. To obtain the numerical results, the 3-D viscous, turbulent, Reynolds-averaged hybrid Navier-Stokes Code TAU of
