Turbulence Effects on Flame Speed and Flame Structure

AIAA Journal, 1979
Turbulence effects on methane-air flames stabilized in grid turbulence were investigated through measurements of flame speed and mean and fluctuating flame temperature profiles. Published turbulent flame speed correlations were able to correlate the experimental flame speed data but were contradictory in indicating flame structure and combustion ...

Turbulent flame–shock interaction inducing end-gas autoignition in a confined space

Combustion and Flame, 2019
To understand the detonation phenomenon in a confined space, especially in a downsized spark ignited engine and in explosion disasters, an experiment on the turbulent flame–shock interaction inducing end-gas autoignition was carried out in an improved ...

Turbulent Forced Diffusion Flames

Combustion and Flame, 1995
A microscale, νβ ∼ νσβ13 is introduced for turbulent diffusion flames, where η and σβ respectively, are the Kolmogorov scale and the flame Schmidt number. In terms of this scale, the turbulent mass transfer integrated over a length l of a liquid fuel is shown to be M′= νBlνβ , where μ is the dynamic viscosity and B is the transfer number, B=(Y0∞

Properties of turbulence in turbulent diffusion flames

Combustion and Flame, 1981
Abstract Measurements of flow velocities and the statistical properties of turbulence such as turbulence intensities, probability density function, autocorrelation, length scales, and power spectrum are carried out by laser Doppler velocimeter, along with the measurements of gas temperature and gas species concentration in turbulent jet flows with ...

Flame profile parameters of horizontal turbulent jets: Experiments, similarity analysis and an integral model

Combustion and Flame, 2019
The present study provides a comprehensive model for flame profile parameters of horizontal turbulent jets, including the flame horizontal projection distance, the flame vertical height, the flame trajectory and the flame cross section radius, which have

Turbulence Production in Premixed Turbulent Flames

Combustion Science and Technology, 1981
Abstract —A second order closure theory developed earlier is used to study the processes influencing the turbulent velocity field in a premixed turbulent flame with degrees of heat release of practical interest. The flow field is chosen so that the time-averaged flame structure is one-dimensional and statistically stationary. Earlier work suggests that

Evolution of averaged local premixed flame thickness in a turbulent flow

Combustion and Flame, 2019
In the combustion literature, contradictory results on the influence of turbulence on the local thickness of a premixed flame can be found and the present paper aims at contributing to reconcile this issue.

Turbulent diffusion flames

Symposium (International) on Combustion, 1973
Experimental results are presented for turbulent diffusion flames of a round jet of hydrogen in a co-flowing stream of air. The aim of the work is to provide comprehensive data which will assist in refining the newer and more-powerful theories coming into use.

Turbulent swirling flame prediction

6th Fluid and PlasmaDynamics Conference, 1973
Finite-difference predictions are made of turbulent boundary layer swirling flames. This paper is concerned essentially with a more accurate simulation of the flow, the turbulence and reaction models. Current developments are discussed. It is demonstrated that the effect of swirl on flame size, shape, and combustion intensity may be represented by ...
