Influence of DC Electric Field on the Propane-Air Diffusion Flames and NO_x Formation

Energies, 2021
The aim of this research is to investigate the effects of a direct current (DC) electric field on the combustion behavior of a co-flow propane diffusion flame. The flame length and NOx emission were observed and measured.

Numerical Investigation of the Effects of Diffusion Time on the Mechanisms of Transition from a Turbulent Jet Flame to Detonation in a H₂-Air Mixture

Fire, 2023
The current study primarily aimed to simulate detonation initiation via turbulent jet flame acceleration in partial-premixed H2-air mixtures. Different vertical concentration gradients were generated by varying the duration of hydrogen injection ...

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.

Non-Premixed Filtered Tabulated Chemistry: Filtered Flame Modeling of Diffusion Flames

Fuels, 2021
The flame front filtering is a well-known strategy in turbulent premixed combustion. An extension of this approach for the non-premixed combustion context has been proposed by means of directly filtering counterflow diffusion flamelets. Promising results

Flamelet Characteristics of Gaseous and Spray Lifted Flames on Two-Dimensional Direct Numerical Simulations

Journal of Fluid Science and Technology, 2008
The detailed behaviors of gaseous and spray lifted flames are studied by two- dimensional direct numerical simulations (DNS), and the characteristics of the flamelets are investigated in terms of two key variables for flamelet modeling, namely mixture ...
