Abstract:
The effect of the addition of nitric oxides (NO and NO$_2$) on rich hydrogen-air flames was studied using the tracer method in numerical simulation. It is shown that the effects of these additives are not similar. Both oxides promote the formation of OH and H$_2$O in the low-temperature zone of the front. The addition of NO reduces the first maximum of the OH profile and the burning velocity. The addition of NO$_2$ increases the first maximum of the OH profile and does not change the burning velocity.
