Asymptotic flame shapes and speeds of hydrodynamically unstable laminar flames
Symposium (International) on Combustion, 1998The self-induced baroclinic instability of flames, the Landau-Darrieus instability, is studied numerically in the nonlinear range. A level set (G equation) based approach accounting for heat-release effects is used to follow the flame response to initial perturbation and shape evolution.

Direct experimental determination of laminar flame speeds
Symposium (International) on Combustion, 1998The stability of premixed flames at ultralow strain rates was assessed experimentally and numerically in the stagnation flow configuration. Results indicate that there are inherent limitations in establishing weakly strained planar flames, and that the accuracy of the laminar flame speeds obtained through linear extrapolations can, thus, be compromised.

Laminar flame speeds of moist syngas mixtures
Combustion and Flame, 2011This work experimentally investigates the effect of the presence of water vapor on the laminar flame speeds of moist syngas/air mixtures using the counterflow twin-flame configuration. The experimental results presented here are for fuel lean syngas mixtures with molar percentage of hydrogen in the hydrogen and carbon monoxide mixture varying from 5 ...

The effect of ozone addition on laminar flame speed
Combustion and Flame, 2015Abstract The effect of ozone (O 3 ) addition on laminar flame speeds ( S L ) across a wide pressure range was investigated experimentally and numerically using three fuels, CH 4 , C 2 H 4 and C 3 H 8 . Enhancement of S L due to O 3 addition was consistently observed for CH 4 and C 3 H 8 mixtures over a range of lean to rich equivalence ratios,

A calculation procedure for the prediction of laminar flame speeds
Combustion and Flame, 1971A computing procedure originally developed for the solution of steady two-dimensional boundary-layer equations has been used successfully to solve the equations of one-dimensional unsteady laminar flame propagation. The procedure has proved to be a simple, flexible, and economical means of predicting the speed of propagation of a steady flame.

Laminar flame speeds and oxidation kinetics of tetrachloromethane
Symposium (International) on Combustion, 1998The laminar flame speeds of blends of tetrachloromethane (CCl 4 ) with methane in air at room temperature and atmospheric pressure were experimentally determined using the counterflow twin-flame technique, varying both the amount of CCl 4 in the fuel and the equivalence ratio of the unburned mixture.

Investigation of High-Pressure Laminar Flame Speed Measurement
Volume 10: Heat Transfer and Thermal Engineering, 2023Abstract Laminar burning speed (LBS) measurements are a significant fundamental experiment in understanding the combustion characteristics of fuels of interest. Such information is necessary for many applications such as engine design or modeling more complicated combustion phenomena.

On the Speed of Strained Laminar Flames in Premixed Systems
Combustion Science and Technology, 1990Abstract An interpretation of the ratio of the rate of creation of products in strained and unstrained laminar flames is shown to provide a convenient estimate for laminar flame speed for use in combustion calculations in which the flame is treated as a discontinuity.

Laminar flame speeds of 2,3,3,3-tetrafluoropropene mixtures
Proceedings of the Combustion Institute, 2017Abstract Laminar flame speeds were determined for stoichiometric difluoromethane-air as well as binary mixtures of difluoromethane/tetrafluoropropene and propane/tetrafluoropropene with air using the vertical tube method. To elucidate important reaction pathways, a detailed chemical mechanism has been compiled for modeling these systems as well as ...
