An experimental and kinetic modeling study of premixed nitromethane flames at low pressure

An experimental and modeling study is reported on three premixed nitromethane/oxygen/argon flames at low pressure (4.655kPa) with equivalence ratios (ϕ) of 1.0, 1.5 and 2.0. Flame species were identified with tunable synchrotron vacuum ultraviolet photoionization. The mole fraction profiles of more than 30 species including intermediates and radicals were obtained by near-threshold burner scan ...

Ignition-promoting effect of NO2 on methane, ethane and methane/ethane mixtures in a rapid compression machine

Autoignition delay times of stoichiometric methane, ethane and methane/ethane mixtures doped with 100 and 270ppm of NO2 have been measured in a RCM in the temperature range 900–1050K and pressures from 25 to 50bar. The measurements show that addition of NO2 to CH4/O2/N2/Ar and CH4/C2H6/O2/N2/Ar mixtures results in a significant reduction in the autoignition delay time and that the ignition-prom...

High pressure oxidation of C2H4/NO mixtures

An experimental and kinetic modeling study of the interaction between C2H4 and NO has been performed under flow reactor conditions in the intermediate temperature range (600–900K), high pressure (60bar), and for stoichiometries ranging from reducing to oxidizing conditions. The main reaction pathways of the C2H4/O2/NOx conversion, the capacity of C2H4 to remove NO, and the influence of the pres...

Numerical simulation of nitrogen oxide formation in lean premixed turbulent H2/O2/N2 flames

Lean premixed hydrogen flames are thermodiffusively unstable and burn in cellular structures. Within these cellular structures the flame is locally enriched by preferential diffusion of hydrogen, leading to local hotspots that burn more intensely than an idealized flat steady flame at comparable inlet conditions. We investigate the impact of this local enrichment on the formation of nitrogen ox...
