Experimental and numerical study of the accuracy of flame-speed measurements for methane/air combustion in a slot burner [PDF]

, 2011
Measuring the velocities of premixed laminar flames with precision remains a controversial issue in the combustion community. This paper studies the accuracy of such measurements in two-dimensional slot burners and shows that while methane/air flame ...

Effect of Equivalence Ratio on Flame Morphology, Thermal and Emissions Characteristics of Inverse Diffusion Porous Burner [PDF]

Journal of Applied Fluid Mechanics
The diffusion porous media combustion is one possible way to eliminate the drawbacks of the existing combustion systems. Inverse diffusion flame (IDF) has features of both premixed and non-premixed flames.

Effects of spacing distance and fuel mass thickness on combustion and flame merging characteristics of two-line pool fires

Case Studies in Thermal Engineering, 2022
Flame merging of line fires is very complex with the interaction of fire dynamics and fluid flow et al., which will often generate different burning behaviors.

Flame projection lengths of horizontally oriented buoyant jet fires under different air pressures

Case Studies in Thermal Engineering, 2021
A horizontal buoyancy-controlled jet fire forms when a gaseous fuel leakage occurs in a pipe or a fuel tank and the fuel is ignited. In this study, the horizontal flame projection length (Lph) from such fires was experimentally investigated under ...
