Combustion processes in supersonic flow
Journal of Propulsion and Power, 1988Three general classes of models that describe the processes occurring in diabatic flow in ducts having supersonic entry conditions are discussed. They are: integral techniques, finite-difference methods, and exact two-dimensional planar flame models formulated on the basis of instantaneous heat release.

Investigation of Mixing and Combustion in Supersonic Flows
The significance of green transportation at hypersonic speeds is the current field of research for space launchers and commercial trans atmospheric vehicles. However, due to their high speeds at Mach > 1, results in a very short residence time of the order of few milliseconds (10 -3 – 10 -4 s) minimizing the chances for air-fuel barely mix and burn.Palateerdham, Sasi Kiran +3 more

Combustion Efficiencies of Supersonic Flames
Journal of Propulsion and Power, 2001Measuredvaluesofcombustionefe ciencyc,whichquantifytheamountofhydrogenfuelthatremainsunburned because the fuel has insufe cient residence time in the reaction zone of a supersonic e ame, are reported. Trends are reported as the fuel e ow rate and the stagnation temperature are systematically varied.

Mixing Problems in Supersonic Combustion
1989The attainment of satisfactory supersonic combustion requires that the fuel and air be mixed to a sufficient extent at the molecular level, at a high enough temperature, so that the combustion reaction is largely complete before the gases leave the combustor. The macro-mixing must be achieved through turbulence, and molecular diffusion effects are only

SUPERSONIC HYDROGEN COMBUSTION STUDIES
1963Abstract : The purpose of this test was to develop diagnostic techniques for the detection of hydrogen combustion in a hypersonic high temperature air stream. This was accomplished by ejecting hydrogen through sonic nozzles oriented normal to the airstream in the case of the flat plate model and at a 45-degree angle downstream in the case of the ...

Supersonic Combustion Ramjet Research
2012Abstract : This basic research task on supersonic combustion ramjets includes work in three primary focus areas: 1) fuel control and fuel injection, wherein fundamental aspects are studied for gaseous, supercritical, and multiphase fuels; 2) ignition, flameholding, and flame propagation in supersonic flows, wherein fundamental aspects are studied with ...
