Fundamentals of Premixed Flames
2016Lavoisier, Berthollet and Dalton were pioneers in the understanding of the mixture composition needed for a flame existence, and in the early 1800s, Sir Humphry Davy created a miner’s lamp with a fine meshed net that improved the safety for mine workers, as the mesh was finer than the quenching distance and hence reduced the number of accidental ...

On the turbulence in premixed flames
Acta Astronautica, 1979The theoretical and experimental validity of the “flame generated turbulence” concept is discussed. Some arguments in favour of a more general concept, the “flame/turbulence interaction”, are proposed. It is concluded that the knowledge of this complex interaction problem requires elaborate investigations of the turbulence spectral behaviour in flames.

Let us consider the motion of flame fronts in flows that can be unsteady and non-uniform. When the length and time scales of the initial flow are larger than those associated with the planar flame (the flame thickness d and the transit time d/uo where uo is the laminar flame speed), the flame front can be considered, in first approximation, as a ...

This chapter will discuss turbulent premixed flames. The distinction between pre-mixed flames and nonpremixed flames is made clear by reviewing the ideal case of each. The ideal nonpremixed flame has fast (equilibrium) chemistry that rapidly adjusts to the local mixture fraction; the mixture fraction is constantly changing.
