Flame Temperatures in Non-Premixed Flames

46th AIAA Aerospace Sciences Meeting and Exhibit, 2008
In preliminary dimensioning of cryogenic LRE injectors, temperatures near the injectors lips must be estimated beforehand to assess potential thermo-structural problems. The usual assumption is that the maximum temperature is the adiabatic flame temperature of the premixed reactants at injection conditions, even if LRE injectors operate in the ...

Premixed Flames

1993
Abstract The deflagrations defined in the last section of Chapter 1 also are called premixed flames and occur in many combustion experiments. If a uniform combustible mixture contained in a tube is ignited by a spark, then a premixed flame propagates through the mixture, moving along the tube at a fairly definite velocity characteristic ...

Non-premixed Flames (Diffusion Flames)

2011
In many combustion processes, the fuel and oxidizer are separated before entering the reaction zone where they mix and burn. The combustion reactions in such cases are called “non-premixed flames,” or traditionally, “diffusion flames” because the transport of fuel and oxidizer into the reaction zone occurs primarily by diffusion.

Statistics of premixed flame cells

Physical Review A, 1991
The statistics of random cellular patterns in premixed flames are analyzed. Agreement is found with a variety of topological relations previously found for other networks, namely, Lewis's law and Aboav's law. Despite the diverse underlying physics, flame cells are shown to share a broad class of geometric properties with other random networks---metal ...

The premixed flame in a counterflow

Combustion and Flame, 1982
Abstract We examine a premixed flame located in a counterflow of fresh cold mixture and hot burnt gas, the latter at a temperature close to that of adiabatic deflagration. A constant density, high activation energy model is adopted, and the steady state response depends essentially on two parameters, the Lewis number, and the temperature of the ...

IMPACT OF STRETCH ON THE FLAME DYNAMICS OF LAMINAR PREMIXED FLAMES

Inter-Noise 2022, 2023
Flame transfer functions (FTF) of laminar premixed flames acoustically forced are analytically investigated and modelled. The study is based on the linearized G-equation, which is used to kinematically track the flame front. In order to incorporate combustion properties, the laminar consumption speed is considered varying depending on the flame front ...
