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.

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 ...

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 ...

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.

Characteristics of Flame Bases for V-Gutters Stabilized Premixed Flames

Volume 8A: Heat Transfer and Thermal Engineering, 2013
The objective of this work is to investigate the flame stabilization mechanism and the impact of the operating conditions on the characteristics of the steady, lean premixed flames. It’s well known that the flame base is very important to the existence of a flame, such as the flame after a V-gutter, which is typically used in ramjet and turbojet or ...

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 ...

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 ...

Lift-off characteristics of turbulent jet diffusion flames

20th Aerospace Sciences Meeting, 1982
A theoretical analysis of turbulent jet diffusion flames is developed in which the flame is regarded as an ensemble of laminar diffusion flamelets that are highly distorted. The flow inhomogeneities are considered to be sufficiently strong to produce local quenching events for flamelets as a consequence of excessive flame stretch.

Effect of turbulence characteristics on local flame structure of H2-air premixed flames

Journal of Turbulence, 2002
Direct numerical simulations (DNS) of turbulent premixed flames are conducted to investigate effects of turbulence characteristics on the local flame structure. A detailed kinetic mechanism including 12 reactive species and 27 elementary reactions is used to represent the H2–air reaction in turbulence. Numerical conditions of DNS can be classified into
