Absorption turbulence-radiation interactions in sooting turbulent jet flames

Journal of Quantitative Spectroscopy and Radiative Transfer, 2017
Abstract The effects of absorption Turbulence-Radiation Interactions (TRI) on radiative heat transfer are investigated along characteristic diametric paths of three ethylene/air flames using a stochastic space and time series model. The three flames cover a wide range of scales and optical thicknesses.

Partially premixed turbulent flame propagation in jet flames

Symposium (International) on Combustion, 1994
Flamelet formulations for premixed and non-premixed combustion are combined in order to treat partiallypremixed combustion in the fast chemistry limit. The flamelet concept for non-premixed combustion is based on the equation for the mixture fraction Z (x, t ), while that for premixed combustion uses a field equation for the scalar field G (x, t ...

Flame Curvature Statistics in Axisymmetric Turbulent Jet Flames

Combustion Science and Technology, 1995
ABSTRACT Flame curvature in axisymmetric turbulent jet flames are obtained experimentally for u'/S L from 0.8–1.5. The measurements indicate that the flame curvature statistics exhibit a substantial change as a function of the axial location in turbulent jet flames primarily due to the evolution of flame wrinkle structures.

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.

Stabilization of lifted turbulent-jet flames

Combustion and Flame, 1994
Abstract Planar imaging measurements of CH, CH4, and temperature are used to evaluate current models for flame stabilization in lifted, turbulent CH4-jet flames. The experimental system consists of two cameras that simultaneously record the instantaneous distributions of species concentration and temperature. Measurements were made in two flames with

Coflowing turbulent jet diffusion flame blowout

Symposium (International) on Combustion, 1989
We present results from an experimental and theoretical investigation into the blowout mechanism in turbulent diffusion flames. The blowout stability limits of coflowing turbulent jet diffusion flames are formulated in terms of a recently proposed flame stabilization mechanism based on the large scale organization of entrainment and mixing observed in ...

TURBULENT JET DIFFUSION FLAMES

Progress in Energy and Combustion Science, 1976
Publisher Summary This chapter discusses the turbulent jet diffusion flames of gaseous fuels. This system is simple compared to that in a diesel or gas turbine engine but nevertheless can throw much light on the mechanisms that are involved in the submodels used in describing the more complex systems.
