Abstract The effects of operating conditions and turbulence on flame front position, turbulent flame speed and flame brush thickness of lean premixed methane/air flames at high pressure are investigated experimentally. A comparison of the measured turbulent flame speeds with existing correlations is presented and discussed.

Abstract The effect of Darrieus-Landau (DL) instability on flame topology and brush thickness was systematically investigated on a planar and Bunsen flame, with the latter used for direct comparison with experimental results from PLIF technique. For planar flame, the flame brush thickness significantly increases with turbulence intensity v ′

Abstract Flame brush thickness is a significant parameter that demonstrates the evolution of turbulent premixed flame. In this paper, the flame height and flame brush thickness of lean turbulent premixed Bunsen CH4/air and C3H8/air flames were investigated under low turbulence intensities.

Evolution of averaged local premixed flame thickness in a turbulent flow
Combustion and Flame, 2019Abstract In the combustion literature, contradictory results on the influence of turbulence on the local thickness of a premixed flame can be found and the present paper aims at contributing to reconcile this issue. First, different measures of local flame thickness in a turbulent flow, e.g. area-weighted and unweighted surface-averaged values of (i)

Implications of laminar flame finite thickness on the structure of turbulent premixed flames
Journal of Fluid Mechanics, 2015A layered description of the structure of turbulent flame brushes is provided for situations featuring large but finite values of the Damköhler number, which correspond to the wrinkled flame regime of turbulent premixed combustion. One special focus of this study is placed on the description of the leading edge of the turbulent flame brush, the role of

Thick Flames with Localised Heat Loss
Combustion Science and Technology, 1990Abstract The solution of the one-dimensional premixed flame equations is considered with Arrhenius kinetics, not only with the assumption of large activation energy, but also large heat release. Previous studies have shown that under these circumstances, the chemical zone widens considerably with the pre-heat zone no longer able to be modelled as a ...

An assessment of stretch effects on a flame tip using the thin flame and thick flame formulations
Combustion and Flame, 2003Flames are stretched due to the interactions between nonuniform flow along the flame, flamefront curvature, and flame motion. Variations in the stretch rate induce local variations in the flame temperature and the mass burning rate. Williams defined flame stretch as the fractional rate of change of an area element on a flame surface [1].

Thermoacoustical noise induced by laminar flame annihilation at varying flame thicknesses
18th AIAA/CEAS Aeroacoustics Conference (33rd AIAA Aeroacoustics Conference), 2012The thermoacoustic response of a harmonically excited laminar lean-premixed flame is investigated with respect to artificially increased flame thicknesses. The flame dynamics is described by solutions of the Navier-Stokes equations plus a combined G-equation progress variable modeling approach based on an unstructured Cartesian method.
