Characteristic of Premixed Hydrogen/Air Tubular Flames in Microcombustor: Effects of Stimulated and Unstimulated Inlet Conditions on Flame Dynamics

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
The present study investigates the characteristics and periodic behavior of H2/air tubular flames in a 1 mm diameter microtube under exciting and nonexciting inlet conditions. Under unstimulated inlet conditions, increasing inlet velocity positively impacted flow stratification and self‐sustaining of the tubular flames, leading to higher maximum ...

Improving Particle‐Burning Efficiency of Pulverized Coal in New Inclined Jet Burners

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
This paper shows an investigation of pulverized coal in new inclined jet burners for improving particle‐burning efficiency through parameter adjustment. The research focuses on the interaction between two oblique jet methane (CH4)/air premixed flame burners and a coal particle jet feeder on an impinging burner. Various parameters such as CH4/air ratios,

Modeling of NOx and Soot Formation in Diesel Combustion Modélisation de la formation des NOx et de la suie en combustion diesel

Oil & Gas Science and Technology, 2006
An approach to model the formation and oxidation or reduction of soot and NO in turbulent diffusion flames is presented. The model is based on the flamelet library approach and extended to account for radiative heat losses in the flame. Due to the rather
