Prediction of GRI-Mech 2.11 |
Target NF1: Maximum NO concentration (at 1.75 cm above the burner)
in a laminar premixed flame of methane
Mixture: CH4-O2-N2 (10.7%/18.8%/70.5%), phi = 1.13
P = 30 torr; flow rate = 1.89e-3 gm/cm^2 s

The sensitivity spectrum shown below was computed with a reaction
mechanism composed of GRI-Mech 1.2 and an evaluated
'literature' (i.e., non-optimized)
set of 99 reactions of nitrogen-containing species
