Flame Broadening Effects on Premixed Turbulent Flame Speed

Combustion Science and Technology, 1992
Abstract Yakhot's turbulent flame speed model is extended to include the effects of scales smaller than the laminar flame thickness (δ). An expression for the turbulent flame speed (ST) as a function of the turbulence intensity (u') and turbulent Reynolds number is derived.

Cascade-Renormalization Theory of Turbulent Flame Speed

Combustion Science and Technology, 1988
Abstract Renormalization group approach to the problem of turbulent flame speed, alternative to that recently adopted by Yakhot is proposed An equation for turbulent flame speed as a function of the turbulent field intensity is derived. The “bending” effect, resembling that known from experiments, is described.

The turbulent flame speed for low-to-moderate turbulence intensities: Hydrodynamic theory vs. experiments

Combustion and Flame, 2017
Abstract This paper, dedicated to Norbert Peters, follows his lead in developing theoretical understanding of the complex flow-turbulence interactions occurring in the propagation of premixed flames. The work is based on the asymptotic hydrodynamic model of premixed flames, where the flame is modeled by a surface that separates unburned and burned ...

Flame characteristics of turbulent lean premixed methane/air flames at high pressure: Turbulent flame speed and flame brush thickness

Proceedings of the Combustion Institute, 2007
Abstract The effects of operating conditions and turbulence on flame front position, turbulent flame speed and flame brush thickness of lean premixed methane/air flames at high pressure are investigated experimentally. A comparison of the measured turbulent flame speeds with existing correlations is presented and discussed.

Investigation of a Turbulent Flame Speed Closure Approach for Premixed Flame Calculations

Combustion Science and Technology, 2000
Abstract A computational model for turbulent premixed gaseous combustion is investigated, where the combustion process is modelled in terms of a single transport equation for a reaction progress variable c. Turbulent closure of the source term of the progress variable is based on a model, where the turbulent flame speed is used in an extension to a ...
