Mapping and structure of inverse diffusion flames of methane
Symposium (International) on Combustion, 1985Six different flame types have been identified in a mapping of inverse methane diffusion flames. Only Types I to III were stable. Types II and III were similar and most “representative” of the IDFs; they also covered more than 50% of the total flame map.

Flame structure of steady and pulsed sooting inverse jet diffusion flames
Proceedings of the Combustion Institute, 2005Abstract In turbulent buoyant fire plumes, local inverse diffusion flames of air injected into gaseous fuel or fuel vapors occur, but little is known about the tendency to form soot and produce thermal radiation in these flame structures. To investigate these phenomena, steady and pulsed normal and inverse jet diffusion flames of methane/air and ...

Quenching limits of inverse diffusion flames with enriched oxygen
Combustion and Flame, 2015Abstract Quenching limits of laminar axisymmetric inverse diffusion flames were observed. Oxygen/nitrogen mixtures were injected into hydrocarbons at 1.01 bar. The limits are correlated with scaling that includes the premixed flame quenching distance and the proportionality between diffusion flame length and oxidizer flow rate.

Soot formation in inverse diffusion flames of diluted ethene
Fuel, 2005Experimental measurements of flame structure and soot characteristics were performed for ethene inverse diffusion flames (IDFs). IDFs are considered as an ideal flow field for studying incipient soot because the soot particles do not experience the oxidation process. In this study, an laser-induced fluorescence image clarified the reaction zone of IDFs

The existence of young soot in the exhaust of inverse diffusion flames
Proceedings of the Combustion Institute, 2002Knowledge of the chemical and physical structure of early soot is useful in the development of sootparticle inception models. This paper examines the hypothesis that soot exiting an inverse diffusion flame is similar in chemical and morphological structure to (1) soot precursor particles and (2) soot that exits underventilated flames.

Soot formation and oxidation in normal and inverse diffusion flames
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2007A numerical study has been carried out to address the sooting characteristics of normal and inverse diffusion flames. The simulation was performed on the basis of single-step kinetics with a laminar flow assumption and non-unity Lewis number. Five different coaxial normal and inverse flame combinations with different momentum ratios have been ...

Abstract The flame appearance and emission characteristics of a LPG inverse diffusion flame (IDF) are studied experimentally in a coaxial burner. Flame length, CO and NOx emissions are examined at different equivalence ratio and swirler vane angle. The flame length of non-swirling IDFs steadily increases with increase in the fuel jet velocity.
