Turbulent burning velocity in combustion chamber of SI engine fueled with compressed biogas
Vietnam Journal of Mechanics, 2015 Turbulent burning velocity is the most important parameter in analyzing pre-mixed combustion simulation of spark ignition engines. It depends on the laminar burning velocity and turbulence intensity in the combustion chamber.

Burning Velocity of Turbulent Methane/Air Premixed Flames in Subatmospheric Environments
ACS Omega, 2020 The aim of our work was to study turbulent premixed flames in subatmospheric conditions. For this purpose, turbulent premixed flames of lean methane/air mixtures were stabilized in a nozzle-type Bunsen burner and analyzed using Schlieren visualization ...

Modeling of the turbulent burning velocity for planar and Bunsen flames over a wide range of conditions [PDF]
Acta Mechanica Sinica, 2021 We develop and assess a model of the turbulent burning velocity sT over a wide range of conditions. The aim is to obtain an explicit sT model for turbulent combustion modeling and flame analysis. The model consists of sub models of the stretch factor and

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.

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).
