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

Auto-Ignition and Flame Stabilization of Hydrogen / Natural Gas / Nitrogen Jets in a Vitiated Cross-Flow at Elevated Pressure

, 2013
The influence of natural gas (NG) on the auto-ignition behavior of hydrogen (H2)/nitrogen (N2) fuel jets injected into a vitiated cross-flow was studied at conditions relevant for practical combustion systems (p = 15 bar, Tcross-flow = 1173 K).

Non-dimensional correlations on flame height and axial temperature profile of a buoyant turbulent line-source jet fire plume

, 2014
This article investigates flame height and axial temperature profile of a buoyant turbulent line-source jet fire plume. Previous correlations have been mainly for axi-symmetrical fire sources or linear pool-type (no initial momentum) fire sources ...

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.

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines

Advanced Engineering Materials, EarlyView.
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Effects of Ammonia (NH3) on Flame Characteristics of Methane (CH4) External Premixed Combustion [PDF]

E3S Web of Conferences
Methane has long been proposed as an alternative to heavy hydrocarbon fuels due to its low carbon content. However, considering the effect of climate change and the need to transition to zero-carbon, ammonia has recently gained popularity as a ...
