Effect of Thermal Conductivity of Tube-Wall on Blow-Off Limit of a Micro-Jet Methane Diffusion Flame

open access: yesEnergy Engineering, 2022
The operating range of the flow rate or flow velocity for the micro-jet flame is quite wide, which can be used as the heat source. In order to optimize the micro-jet tube combustor in terms of the solid material, the present paper numerically ...

A novel diffusion flux modeling for laminar premixed flame simulation with OpenFOAM

open access: yesResults in Engineering, 2023
In this study, we developed a mass diffusion coefficient model for premixed combustion to reduce the computational time, in mixture-averaged diffusivities to serve as a microcomputer resource.

Stability of diffusion flames under shear flow: Taylor dispersion and the formation of flame streets [PDF]

open access: yesCombustion and Flame, 2023
Diffusion flame streets, observed in non-premixed micro-combustion devices, align parallel to a shear flow. They are observed to occur in mixtures with high Lewis number ($Le$) fuels, provided that the flow Reynolds number, or the Peclet number $Pe ...

Numerical Studies of Premixed and Diffusion Meso/Micro-Scale Flames

open access: yesEnergy Procedia, 2017
Abstract This work reports a numerical investigation of premixed and diffusion meso/micro-scale flames, with homogeneous reactions, for two different cases involving CH 4 /air premixed dynamics flames and co-flow diffusion flame with H 2 /N 2 mixture.

Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner

open access: yesJournal 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 ...

Process and properties of spray-aluminized coating on cast iron

open access: yes工程科学学报, 2017
Aluminum-based coatings were prepared by flame spraying. After remelting and diffusion treatment, the phase, composition, friction and corrosion resistance were analyzed experimentally by using scanning electron microscopy, X-ray diffraction, energy ...
