Analysis of auto-ignition of heated hydrogen-air mixtures with different detailed reaction mechanisms [PDF]
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

Ignition by Hot Transient Jets in Confined Mixtures of Gaseous Fuels and Air
Ignition of a combustible mixture by a transient jet of hot reactive gas is important for safety of mines, prechamber ignition in IC engines, detonation initiation, and novel constant-volume combustors.

Ultra-Lean Premixed Turbulent Combustion: Challenges of RANS Modelling
The main challenge of improving spark ignition (SI) engines to achieve ever increasing thermal efficiencies and near-zero pollutant emissions today concerns developing turbulent combustion under homogeneous ultra-lean premixed mixtures (HULP).
