Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner
Journal of Thermal Science and Technology, 2018 Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner was studied. A diffusion flame was stabilized in the gap between opposed ports ejecting fuel and oxygen gases, and its thickness which depended on the gap distance between burner ...

Experimental Study of Stretched Premixed Flame Stabilized in a Flat Channel near a Heated Wall
Metals, 2023 In this work, the behavior of a lean premixed stretched flame stabilized in a flat channel near a heated wall was studied. Dependences of the flame front position on the stretch rate parameter at temperatures of the heated wall of 1000 and 1200 K and the

Flame Annihilation Displacement Speed and Stretch Rate in Turbulent Premixed Flames
Flow, Turbulence and Combustion, 2019 This paper examines the dynamics of flame annihilation in turbulent premixed flames using a DNS dataset of Haghiri et al. (J. Fluid Mech. 843, 29 2018). Two theoretical frameworks are considered. The relative contributions of the reaction rate, normal diffusion and flame curvature to the flame displacement speed are first considered.

Influences of stretch and curvature on the temperature of stretched cylindrical diffusion flames
Journal of Thermal Science and Technology, 2016 The structure of a counterflow-type cylindrical diffusion flame was studied experimentally to determine the effect of stretch and curvature. The cylindrical flame used in this study had a concave curvature with respect to the fuel stream.

Flame Structure, Burning Velocity and Burning Rate in Stretch Controlled Premixed Flame
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2004 We discuss the effect of stretch rate on the flame structure, the burning velocity and the burning rate in premixed counter flow flat flame. Numerical computations taking into account detailed chemical kinetics and multi-component diffusion are conducted. The burning velocity increases with increasing the stretch rate.

Characterization of jet-in-hot-coflow flames using tangential stretching rate [PDF]
Combustion and Flame, 2019 Abstract This article presents a numerical study of a jet-in-hot-coflow (JHC) burner which emulates Moderate or Intense Low-oxygen Dilution (MILD) conditions. Such combustion regime offers reduction in pollutant emissions and improvements in efficiency.
