Abstract

Premixed ammonia/nitric oxide flame was simulated using the Lindstedt 1994 and Miller-Bowman 1989 reaction mechanisms in CHEMKIN. The predicted laminar burning velocities compared well with limited measured values in the literature. The effects of unburnt mixture temperature and pressure on laminar burning velocity, flammability limits, adiabatic flame temperature and species profiles were studied. The unburnt mixture temperature had a positive impact on both the laminar burning velocity and the adiabatic flame temperature, and it extended the ammonia-rich flammability limit. The pressure had a marginally negative influence on the laminar burning velocity, while it had a slightly positive effect on the adiabatic flame temperature. © 2003 Elsevier Ltd.
