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

Engineering 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.

Alternative fuels for spark-ignition engines: mixing rules for the laminar burning velocity of gasoline-alcohol blends [PDF]

, 2012
Experimental measurements of the laminar burning velocity are mostly limited in pressure and temperature and can be compromised by the effects of flame stretch and instabilities.

Measurements of the laminar burning velocity for propane: Air mixtures

Advances in Mechanical Engineering, 2016
In this research, an experimental setup was built based on using K-type thermocouples inserted in a cylindrical vessel and coupled with a computer system to enable online reading of flame speed for propane-air mixtures.

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 ...

Propagation of the First Flames in Type Ia Supernovae [PDF]

, 2006
We consider the competition of the different physical processes that can affect the evolution of a flame bubble in a Type Ia supernovae -- burning, turbulence and buoyancy.

The Thermonuclear Explosion Of Chandrasekhar Mass White Dwarfs [PDF]

, 1996
The flame born in the deep interior of a white dwarf that becomes a Type Ia supernova is subject to several instabilities. We briefly review these instabilities and the corresponding flame acceleration. We discuss the conditions necessary for each of the
