Overview of Autoignition and Flame Propagation Properties for Ammonia Combustion

AIAA Journal, 2023
With the increasingly stringent [Formula: see text] emission, next-generation propulsion systems with chemical reaction combustion involved need to operate with carbon-free fuels, such as ammonia or hydrogen.

End-gas autoignition and knocking combustion of ammonia/hydrogen/air mixtures in a confined reactor

International journal of hydrogen energy, 2022
End-gas autoignition and detonation development in ammonia/hydrogen/air mixtures in a confined reactor is studied through detailed numerical simulations, to understand the knocking characteristics under IC engine relevant conditions.

NH3 vs. CH4 autoignition: A comparison of chemical dynamics

Combustion theory and modelling, 2021
In order to obtain physical insights on ammonia combustion, which is characterised by exceptionally long ignition delays and increased NOx emissions, the autoignition dynamics of an ammonia/air mixture is analysed using the diagnostics tools derived from

Chemical dynamics of the autoignition of near-stoichiometric and rich methanol/air mixtures

Combustion theory and modelling, 2021
The homogeneous, isochoric and adiabatic autoignition of rich methanol mixtures is analysed using algorithmic tools of Computational Singular Perturbation.
