Turbulent flame speed and thickness: phenomenology, evaluation, and application in multi-dimensional simulations
Andrei Lipatnikov,Jerzy Chomiak +1 more
TL;DR: Several models have been suggested utilizing this approach and the first laboratory and industrial applications of them have shown encouraging results as mentioned in this paper, and these successful applications motivate a thorough discussion and further development of the approach.

Turbulent flows with premixed reactants
TL;DR: In this article, the authors considered premixed turbulent combustion and showed that the mean rate of heat release is strongly influenced by the turbulence rather than by chemical kinetic factors, and argued that such models provide the best available compromise between complexity and generality of application.
Journal ArticleDOI
Turbulence and turbulent flame propagation—A critical appraisal
TL;DR: In this article, the compatibility of theories of turbulence with different turbulent flame models is discussed, and it is suggested that the turbulent Reynolds number, Rλ, of the reactants is an important controlling parameter in turbulent flame propagation.

Interaction effects in turbulent premixed flames
Knc Bray,Paul A. Libby +1 more
TL;DR: In this article, the authors apply the Bray-Moss model for turbulent, premixed combustion to plane, oblique combustion waves and make predictions of the flame speed and the structure of the reaction zone in cases where turbulent mixing is rate limiting.

On the propagation of turbulent flames
Ahto Palm-Leis,Roger A. Strehlow +1 more
TL;DR: In this article, Schlieren observations of the growth and structural changes in outwardly propagating spherical flames in laminar and isotropic turbulent flow fields are presented and discussed, both in light of the new definition and the cellular instability behaviour of the flame.

Investigation of Turbulent Flames
TL;DR: In this paper, a theory of turbulent burning velocity has been developed to explain the production of turbulence by the turbulent flame and a comparison of calculated maximum turbulence intensity values with the turbulence intensities that correspond to the measured turbulent burning•velocity data supports this theory.
Journal ArticleDOI
Flame Turbulence Measurements by the Method of Helium Diffusion
TL;DR: In this paper, a technique for measuring transverse turbulence intensity in flames which makes use of the diffusion of helium is described, and results obtained in highly turbulent flames stabilized on various baffles in a 5 cm×20 cm duct are given, compared with results obtained under comparable cold flow conditions.
Journal ArticleDOI
Applications of the Electronic Probe to the Study of Turbulent Flames
TL;DR: In this article, a negatively biased bare wire probe with suitable amplification and pulse height discrimination is used to detect flame fronts in turbulent motion, and the treatment of data and the precision and limitations of the method are discussed.
Structure and Propagation of Turbulent Bunsen Flames
TL;DR: In the assessment of research objectives after World War II, it was brought out that little effort had yet been expended on an understanding of turbulent flames as discussed by the authors, and the present report deals exclusively with a second stage of work which was carried out between November 1954 and August 1959.
