Effects of curvature on flame acceleration in micro channels

, 2022
The effects of channel curvature on the flame propagation are examined for premixed flames in micro channels. Previous studies have shown that curved channels can enhance the flame stretching, which can significantly increase the flame propagation speed.

Model constant C of turbulent NO reaction time model

Case Studies in Thermal Engineering, 2017
The NO concentration of turbulent jet flames with different fuel, jet velocity, and jet diameter are simulated with the turbulent NO reaction time model. The predicted NO profile has very good agreement with the experimental data.

The ozone flame

, 1985
The Ozone flame structure is analyzed from the point of view of asymptotic methods, using the fact that the ratios of the characteristic times associated with the different reactions, which change with the flame temperature and therefore with the initial

Fundamental studies of combustion of droplet and vapour mixtures [PDF]

, 2010
There are few experimental data of a fundamental nature that clearly demonstrate the similarities and differences in burning rates between single phase and two phase combustion, either in laminar or turbulent conditions. Such data are essential towards a

Influence of Annular Flow Area and a 30-Degree Impingement Angle on Methane/Oxygen Diffusion Flame Stability

Methane
This work examined the effects of secondary annular flow area on flame stability in an experimental diffusion flame burner. The burner was composed of a horizontally mounted, rectangular chamber that utilized a retractable spark plug for ignition and an ...
