Analysis of auto-ignition of heated hydrogen-air mixtures with different detailed reaction mechanisms [PDF]
, 2011 Auto-ignition processes of hydrogen, diluted with nitrogen, in heated air are numerically investigated by means of an unsteady laminar flamelet approach in mixture fraction space. The focus is on the auto-ignition delay time and the most reactive mixture
