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.

Laminar Flame Speeds of Propane-Nitrous Oxide Mixtures
47th AIAA Aerospace Sciences Meeting including The New Horizons Forum and Aerospace Exposition, 2009Mixtures of propane with nitrous oxide at various nitrogen dilution levels (N2O/(N2O + N2)) were studied to experimentally and numerically determine the adiabatic, laminar flame speed at atmospheric and near-atmospheric pressure (0.8 atm). Over virtually all equivalence ratios examined, a previously integrated chemical mechanism underpredicted the ...

Laminar Flame Speed Characterization of Synthetic Gasoline Components
SAE Technical Paper Series, 2014<div class="section abstract"><div class="htmlview paragraph">This paper investigated the laminar flame speed behavior of a matrix of ten spark-ignition fuels and fuel components using a spherical combustion bomb. The analysis methodology relied solely on the in-bomb pressure data. For each fuel measurements were performed at five different

Determination of laminar flame speeds from nozzle-generated counterflow flames
2008The accuracy of the counterflow, twin-flame technique for the determination of laminar flame speeds was examined analytically and numerically. The analysis was conducted by using multiple-expansion, high activation energy asymptotics while the numerical simulation incorporated detailed chemistry and transport.

The Relationship of the Laminar Flame Width to Flame Speed
Combustion Science and Technology, 1986Abstract The width ( δ ) of a laminar flame is often characterized as a basic property of the flame and is sometimes used in turbulent combustion models to categorize the turbulence scale of the mixture. From computed flame speeds and temperature profiles of C3H8/Oa/Ns (o=1) flames we have determined widths, using definitions based on ( dT*sol;dx)max ...

Laminar flame speed of Fossil/Air and Biofuels/Air Combustion
11th International Energy Conversion Engineering Conference, 2013Traditional fossil fuels are considered to be largely responsible for the atmospheric environmental degradation. Biofuels can contribute to reducing the dependency on fossil fuels and to lowering greenhouse gas emissions due to aviation transport and can be considered as both renewable and sustainable energy sources. Indeed, biofuels are recognized as “

Laminar Flame Speeds of Gasoline Surrogates Measured with the Flat Flame Method
Energy & Fuels, 2016The adiabatic, laminar flame speeds of gasoline surrogates at atmospheric pressure over a range of equivalence ratios of Φ = 0.8–1.3 and unburned gas temperatures of 298–400 K are measured with the flat flame method, which produces a one-dimensional flat flame free of stretch.

A numerical study of laminar flame speed of stratified syngas/air flames
International Journal of Hydrogen Energy, 2018Abstract Numerical simulations are performed to study the flame propagation of laminar stratified syngas/air flames with the San Diego mechanism. Effects of fuel stratification, CO/H2 mole ratio and temperature stratification on flame propagation are investigated through comparing the distribution of flame temperature, heat release rate and radical ...

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,

Laminar Flame Speed of Lean Premixed H2/CO/Air Flames
2017This chapter provides an in-depth study on the laminar flame speed of lean premixed H2/CO/air flames. The experimentation covered a broad range of the H2/(H2 + CO) volumetric ratio. The performance of chemical kinetic mechanisms was verified using the new data. The flame temperature and the chemical kinetics was studied and a semi-empirical correlation
