Does sensitivity of measured scaling exponents for turbulent burning velocity to flame configuration prove lack of generality of notion of turbulent burning velocity? [PDF]

Combustion and Flame, 2016
There exists a large scatter in reported scaling (power) exponents q characterizing response of turbulent flame speed St or burning velocity Ut to changes of various factors such as the root-mean-square turbulent velocity u′, integral length scale L or laminar flame speed SL0, e.g. St∝u′^q. This scatter is often interpreted as lack of generality of the

The turbulent burning velocity for large-scale and small-scale turbulence

Journal of Fluid Mechanics, 1999
The level-set approach is applied to a regime of premixed turbulent combustion where the Kolmogorov scale is smaller than the flame thickness. This regime is called the thin reaction zones regime. It is characterized by the condition that small eddies can penetrate into the preheat zone, but not into the reaction zone.By considering the iso ...

The turbulent burning velocity of iso-octane/air mixtures [PDF]

Combustion and Flame, 2012
Turbulent burning velocities of iso-octane air mixtures have been measured for expanding flame kernels within a turbulent combustion bomb. High speed schlieren images were used to derive turbulent burning velocity.

Turbulent Burning Velocity of High Hydrogen Flames

Journal of Engineering for Gas Turbines and Power
Abstract The turbulent burning velocity (ST) is one of the most important combustion properties controlling combustor operability limits, directly influencing blowoff, flashback, and combustion instabilities. Hydrogen has particularly significant influences on the turbulent flame speed.

Flame structure, turbulent burning velocity and its unified scaling for lean syngas/air turbulent expanding flames

International Journal of Hydrogen Energy, 2021
A systematic experimental study of lean premixed syngas/air turbulent expanding flames has been conducted under a wide range of turbulence intensities (0–3.54 m/s), initial pressures (0.5–5 bar), and hydrogen volumetric fractions up to 80% (20%, 50% and ...

Self-similar propagation and turbulent burning velocity of CH4/H2/air expanding flames: Effect of Lewis number

Combustion and Flame, 2020
In this study we clarify the role of differential diffusion characterized by effective Lewis number, Leeff, on the self-similar accelerative propagation and the associated turbulent burning velocity of turbulent expanding flames.
