Premixed flame

TL;DR: Several models have been suggested utilizing this approach and the first laboratory and industrial applications of them have shown encouraging results as mentioned in this paper, and these successful applications motivate a thorough discussion and further development of the approach.

TL;DR: In this article, the laminar burning velocities and Markstein lengths of natural gas-hydrogen-air flames were obtained at various ratios of hydrogen to natural gas (volume fraction from 0 to 100%) and equivalence ratios.

TL;DR: In this article, a model of turbulent sub-grid scale flame speed for premixed combustion is proposed and tested in Large Eddy Simulation (LES), based on writing the unresolved flame surface density in terms of a general power-law expression that involves an inner cutoff scale.

TL;DR: In this article, the laminar flame speeds of methane + air and propane + air mixtures, with and without the addition of stoichiometrically small amounts of hydrogen, have been determined by first measuring the flame speeds with stretch and then linearly extrapolating these values to zero stretch.

TL;DR: In this paper, an experimental investigation of acoustically forced lean premixed turbulent bluff-body-stabilised flames in an enclosure short enough so that no coupling of the combustor downstream acoustics occurred for the frequencies studied here, which allows an unambiguous examination of the flame response to inlet velocity fluctuations.
