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.

Dynamics of Laterally Propagating Flames in X-ray Bursts. I. Burning Front Structure [PDF]

, 2019
We investigate the structure of laterally-propagating flames through the highly-stratified burning layer in an X-ray burst. Two-dimensional hydrodynamics simulations of flame propagation are performed through a rotating plane-parallel atmosphere ...

Experimental Comparison of Working Region, Flame Stability, and Flame Height of LPG, DME, and DME-mixed LPG in an Atmospheric Diffusion Cylindrical Burner

International Journal of Technology, 2020
This study investigates the possibility of substituting liquid petroleum gas (LPG) with dimethyl ether (DME) by considering the procedures of burner design in terms of working region, flame stability, and flame height. An experiment was designed using

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.

Scaling, Propagation, and Kinetic Roughening of Flame Fronts in Random Media [PDF]

, 1995
We introduce a model of two coupled reaction-diffusion equations to describe the dynamics and propagation of flame fronts in random media. The model incorporates heat diffusion, its dissipation, and its production through coupling to the background ...

An experimental study on coflow diffusion combustion in a pellet-packed bed with different bed lengths [PDF]

Royal Society Open Science, 2018
In experimental investigations on axial symmetry, over-ventilated CH4/air diffusion combustion in a packed bed is executed to study the height, shape and stability of the flame.

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 ...
