Characteristics of ammonia/N2/O2 laminar flame in oxygen-enriched air condition

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Ammonia is regarded as one of the alternative fuels and regarded as a “hydrogen carrier”. Ammonia is an easily-liquefiable fuel. Therefore, it is a suitable fuel for transportation and storage.

The Effect of Initial Temperature on Burning Velocity of Hydrogen – Air Mixtures [PDF]

open access: yesEngineering and Technology Journal, 2007
In present work, the burning velocity of hydrogen-Air mixtures varies with hydrogen concentration and initial temperature of the unburned mixture. Laminar flame speed has been measured experimentally inside tube using the optical technique.

Turbulent and Stable/Unstable Laminar Burning Velocity Measurements from Outwardly Propagating Spherical Hydrogen-Air Flames at Elevated Pressures

open access: yesJournal of Thermal Science and Technology, 2006
The laminar burning velocity of pre-mixed hydrogen-air mixtures was measured in a fan stirred combustion bomb. Unstretched laminar burning velocities and Markstein lengths were obtained at 0.10MPa for equivalence ratios of 0.4, 0.6, 0.8 and 1.0 using ...

Influence of Oxymethylene Ethers (OMEn) in Mixtures with a Diesel Surrogate

open access: yesEnergies, 2021
Within this work the effects of blending oxymethylene ethers (OMEn) to a diesel surrogate (50 mol% n-dodecane, 30 mol% farnesane, and 20 mol% 1-methylnaphthalene) were investigated by performing two different types of experiments: measurements of the ...

Measuring laminar burning velocities

open access: yes, 2010
The laminar burning velocity of a fuel is the rate of normal propagation of a 1D flame front relative to the movement of the unburned gas. This is a fundamental property of a fuel that affects many aspects of its combustion behaviour. Experimental values are required to validate kinetic simulations, and also to provide input for models of flashback ...

Experimental study on premixed flame acceleration in closed pipe [PDF]

open access: yes, 2013
An experimental study has been carried out to investigate the flame acceleration in closed pipe. A horizontal steel pipe, with 2 m long and 0.1 m diameter, giving length to diameter (L/D) ratio of 20 was used in this project.

Laminar burning velocities and Markstein numbers of hydrocarbonair flames [PDF]

open access: yesCombustion and Flame, 1993
Effects of positive flame stretch on the laminar burning velocities of hydrocarbon/air mixtures were studied experimentally using outwardly propagating spherical flames. The test conditions included propane, methane, ethane, and ethylene-air flames at various fuel-equivalence ratios and normal temperature and pressure.
