Flame structure transition and instability excitation by pilot fuel in a centrally staged combustor
The Physics of FluidsThe pilot stage plays a crucial role in central-staged combustion technology. This study aimed to investigate the impact of the jet-type pilot stage on the flame structure and combustion instability in a novel strong coupled centrally staged swirl gas ...

Laminar hydrocarbon flame structure
Combustion, Explosion, and Shock Waves, 2009From the very first experimental studies, based essentially on flame propagation velocity and flame emission measurements, successive improvements in analytical and numerical techniques have contributed to make the analysis of laminar flame structure a powerful tool for extending the knowledge on combustion chemistry, thermodynamics, and transport ...

ACS Applied Materials and Interfaces
Biobased-functionalized metal-organic frameworks (Bio-FUN-MOFs) stand out from the crowd of candidates in the flame-retardant field due to their multipathway flame-retardant mechanisms and green synthesis processes.

Symposium (International) on Combustion, 1998
Quantitative CN, OH, and OH rotational temperature, and velocity two-dimensional profiles have been imaged using planar laser-induced fluorescence (PLIF) imaging or particle-imaging velocimetry (PIV) during ignition and deradiative extinguishment of cyclotrimethylene-trimitramine, (RDX) at three different heat flux levels.

Counterflow heptane flame structure
Proceedings of the Combustion Institute, 2000Results are reported for thermocouple and gas-chromatographic measurements of profiles of temperature and of concentrations of C 7 H 16 , C 5 H 10 , C 4 H 8 , C 4 H 6 , C 3 H 6 , C 2 H 6 , C 2 H 4 , C 2 H 2 , CH 4 , CO, and CO 2 in two laminar counterflow n -heptane flames having measured flame temperature of 2100 K, at an oxidizerside potential-flow

Solid Propellant Flame Structure
MRS Proceedings, 1995AbstractPlanar Laser Induced Fluorescence (PLIF), UV/Vis Absorption, and thermocouple measurements were done for HNF, RDX, HMX, and XM39 deflagration with and without CO2 laser-support. RDX and especially HNF have very short self-deflagration flame length scales. HMX and XM39 have taller self-deflagration flames.

The state-of-the-art in modelling laminar flames is reviewed in three selected areas, viz., (i) derivation of systematically reduced mechanisms, (ii) asymptotic approaches to investigate the structure of steady flames, and, (iii) numerical approaches to the computation of unsteady flames. For each of these topics representative examples are discussed.

C. K. Law addressed the issue of discrepancies between numerical simulations and experimental observations. He pointed out that simulations employ kinetic and thermal data which are known only approximately. Likewise, experimental data, as recorded, may not conform strictly to conditions experienced by the flame.
