Adiabatic flame temperatures are of comparable magnitude for both stoichiometric hydrogen-air and gasoline (analogously isooctane)-air mixtures; Verhelst and Wallner (2009) [15] report values of 2390 K for stoichiometric hydrogen-air and 2276 K for stoichiometric isooctane-air (both values at 300 K and 1 atm initially).
The assumption is made that both zone at the same pressure and the ignition temperature is the adiabatic flame temperature based on the mixture enthalpy at the onset of combustion.
This is the direct consequence of the higher adiabatic flame temperature when increasing the oxygen concentration.
NO and CO concentrations and adiabatic flame temperature for nine cases are comparatively plotted in Figures 24 which show that there is a reasonable agreement between the generated five-step mechanisms and the detailed GRI 3.

The study shows the influence of the oxygen dilution rate on the adiabatic flame temperature (AFT) as well as on the stoichiometric ratio (Fig.
Flame temperature is calculated as equilibrium adiabatic flame temperature (Olikara, Borman 1975).

He then deals with the energetics of chemical compounds used as propellants and explosives, such as heat of formation, heat of explosion, adiabatic flame temperature, and specific impulse.
AlliedSignal engineers explain that the LPP combustor burns very lean fuel/air mixtures, resulting in an adiabatic flame temperature below N[O.
