Flame Propagation Speed Test of Biomass Gas

Applied Mechanics and Materials, 2014
The Bunsen burner was improved to measure the flame propagation speed of biomass gases with different kinds of components using angle method on test bench. The influences of different components, especially CO2, on flame speed propagation and the relations between flame speed and primary air ratio were measured and analyzed.

Consistent definitions of “Flame Displacement Speed” and “Markstein Length” for premixed flame propagation

Combustion and Flame, 2015
Abstract The definition of the flame displacement speed (FDS), often used to characterize the dynamical properties of premixed flames, is generally ambiguous because, except for a steadily propagating planar flame, the mass flow rate through the combustion region varies with distance through the flame and one is therefore faced with the difficulty of

Effects of electric field intensity and distribution on flame propagation speed of CH4/O2/N2 flames

Fuel, 2015
Abstract In order to study the effects of electric field intensity and distribution on flame propagation speed, the paper investigated the flame propagation of premixed CH 4 /O 2 /N 2 mixtures under direct-current (DC) electric fields at an excess air ratio of 1.4.

Transient flame propagation process and flame-speed oscillation phenomenon in a carbon dust cloud

Combustion and Flame, 2012
A detailed numerical study was conducted to understand the transient flame propagation process and the flame-speed oscillation phenomenon in a carbon dust cloud. The modeling included the solution of a set of time-dependent conservation equations developed for the gas phase and the particle phase in a spherical coordinate.

Flame propagation speed and Markstein length of spherically expanding flames: Assessment of extrapolation and measurement techniques

Proceedings of the Combustion Institute, 2019
Abstract Laminar burning velocities are of great importance in many combustion models as well as for validation and improvement of chemical kinetic schemes. Determining laminar burning velocities with high accuracy is quite challenging and different approaches exist.

Flame speed scaling in autoignition-assisted freely propagating n-heptane/air flames

Proceedings of the Combustion Institute, 2021
Abstract Autoignition and flame propagation embody different controlling mechanisms for flame stabilization in various modern combustion devices such as the internal combustion engines with hot air and elevated pressure environments. In this study, the flame structure and propagation speed scaling for n-heptane/air mixtures are numerically ...
