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

Journal 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 (OME_n) in Mixtures with a Diesel Surrogate

Energies, 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

, 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 ...

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

Combustion 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.

Experimental study on the combustion characteristics of hydrogen/ammonia blends in oxygen

Case Studies in Thermal Engineering
Carbon-free ammonia and hydrogen have various disadvantages when used individually, which limits their application as clean energies. These disadvantages can be effectively overcome by combining them as ammonia/hydrogen mixtures in a rational manner.
