The turbulent burning velocity of methanol–air mixtures [PDF]
Fuel, 2014 Methanol is a sustainable and versatile alternative fuel for spark-ignition engines and other combustion applications. To characterize the combustion behavior of this fuel, a good understanding of the factors affecting its turbulent burning velocity is required.

Turbulent burning velocity measurements: Extended to extreme levels of turbulence [PDF]
Proceedings of the Combustion Institute, 2017 Abstract Previous measurements of turbulent burning velocity ( S T ) have been reported by Gulder and colleagues for intense levels of turbulence, defined to be u ’⁄ S L values between 12 and 24, and normalized integral scales ( L x ⁄ δ L ) up to 46.

Evolution of Turbulent Burning Velocity and Turbulence Intensity During Aluminum Flame Propagation
Chemical Engineering TransactionsBurning velocity, i.e. the consumption rate of the reactant by the flame front, is a key parameter for modelling flame propagation during accidental gas or dust explosions.

Propagation Properties of Turbulent Premixed Flames Neutral for Thermo-Diffusive Effects
International Journal of Automotive Engineering, 2020 Burning velocity is one of the important properties of premixed turbulent flames. Premixed turbulent flames are, in general, subjected to the thermo-diffusive effects in addition to the increase in the flame front area due to the influence of turbulence.

Turbulent burning velocity and thermodiffusive instability of premixed flames
Physical Review E, 2023 Reported in the paper are results of unsteady three-dimensional direct numerical simulations of laminar and turbulent, lean hydrogen-air, complex-chemistry flames propagating in forced turbulence in a box. To explore the eventual influence of thermo-diffusive instability of laminar flames on turbulent burning velocity, (i) a critical length scale Λn ...

Direct determination of burning velocity during aluminium flame propagation
Chemical Engineering Transactions, 2022 Numerical simulations are needed to model accurately the consequences of dust explosions. One key parameter for modelling the flame propagation is the burning velocity (ie the consumption rate of the reactants by the flame front).

Journal of Thermal Science and Technology, 2012 Burning velocity of spherically propagating turbulent flames kept increasing with flame propagation. On the other hand, turbulent burning velocity obtained from burner stabilized flame is constant for a given turbulence intensity.

On defining the turbulent burning velocity in premixed V-shaped turbulent flames [PDF]
Combustion and Flame, 1984 Abstract Turbulent buring velocity S t is determined for six premixed V-shaped turbulent flames. In addition to defining S t with respect to the conventional flame surface, a definition based on an effective flame orientation is proposed. The results based on the flame surface increase significantly with distance from the flame stabilizer ...
