Some flame characteristics of motor fuels

Proceedings of the Symposium on Combustion, 1928
In order to obtain some information as to the cause of the “pink” or knock of motor fuels, a photographic study has been made of the movement of flames, simultaneously with measurements of the development of pressure, during the explosion of the charge in an engine cylinder.

Flame Holding and Combustion Characteristics of a Geometrical Flame Holder

Heat Transfer: Volume 3, 2008
Flame Stabilization in a high-speed premixed environment requires the presence of a mechanism to stabilize the flame. Bluff bodies or geometrical flame holders introduce a recirculation zone that anchor the flame. The current study considers the influence of equivalence ratio and the boundary layer state at the trailing edge of the flame holder on the ...

Flame characteristics and emission

Spectrochimica Acta, 1961
Abstract Several combustion characteristics which play a role in the radiation of flames are reviewed. The limits of inflammability of various combustible mixtures used in analytical flame spectroscopy, together with their ignition temperature, burning and detonation velocity and detonation pressure are examined briefly.

Flame characteristics of hydrogen-enriched methane–air premixed swirling flames

International Journal of Hydrogen Energy, 2007
Abstract The effect of hydrogen addition in methane–air premixed flames has been examined from a swirl-stabilized combustor under unconfined flame conditions. Different swirlers have been examined to investigate the effect of swirl intensity on enriching methane–air flame with hydrogen in a laboratory-scale premixed combustor operated at 5.81 kW. The

Frequency characteristics of a laminar flame

Journal of Applied Mechanics and Technical Physics, 1974
A theoretical study is made of the effect of harmonic pressure oscillations on a flat laminar flame. Frequency characteristics of the flames are obtained at amplitudes of the pressure oscillations which are small compared with the average pressure. It is established that in a broad range of frequencies the disturbances in the integral rate of heat ...

Characteristics of tubular flames

Progress in Energy and Combustion Science, 1993
Abstract A tubular flame is established in a stretched vortex flow. This flame is long and its cross-sectional shape is cylindrical; hence, the shape is exactly tubular. From a fundamental viewpoint, tubular flames have two different aspects from the usual flames.

Emission Characteristics of Syngas Flames

Heat Transfer, Volume 2, 2006
Synthesis gas or "Syngas" is being recognized as a viable energy source worldwide, particularly for stationary power generation due to its wide flexibility in fuel sources and superior pollutants characteristics. Although its composition may vary significantly, it generally contains CO and H2 as the dominant fuel components with varying amount of ...

Characteristics of microscale diffusion flames

Proceedings of the Combustion Institute, 2002
This paper describes an investigation of microscale diffusion flames, which are potential sources of energy for future micro power generators. Of particular interest was the extinction process, as it would have direct bearing on the minimum size and power of the devices in which such flames would be used.

Radiative characteristics and flame structure of small-pool flames

Fire Technology, 1996
A new way of using thermography for radiative objects like pool flames has been developed by the author. The thermography method, which has already been applied to large pool fires, is applied to small pool flames in this paper. The radiative characteristics and flame structure of small pool flames are considered by examining flame temperature ...

Combustion characteristics of monopropylpentaborane flames

Symposium (International) on Combustion, 1965
An account is given of several complementary experiments on the combustion of fuel-lean monopropylpentaborane-air mixtures: viz., determination of burning velocities; measurement of heat-release rates in the well-stirred reactor; determination of composition and temperature profiles in the reaction zone of a flat flame at reduced pressure; analysis of ...
