Testing detailed combustion mechanisms typically concludes that some mechanisms reproduce the experimental data well at most conditions but are inaccurate at other conditions. However, other mechanisms may perform well under these conditions. A better mechanism ("mosaic mechanism") may be obtained by identifying the overall best-performing mechanis...

Investigating the methanol (CH 3 OH) / nitrogen-oxides (NOx) combustion system is an important task since methanol is a promising alternative to fossil fuels, and its interactions with nitrogen oxides are significant due to environmental effects. The performances of the recently available detailed mechanisms in simulating the experimental results a...

A comprehensive quantitative comparison of 18 detailed reaction mechanisms was performed using a large collection of experimental data on the combustion of neat NH3 and NH3/H2 fuel mixtures. Results showed that even though some models can reproduce the experimental results very well under some circumstances, their overall performance should be impr...

Introduction Ammonia (NH3) is a promising carbon-free fuel because it can be used in a sustainable and recyclable loop for energy production. It is often blended with other fuels in practical applications. One of the most often used co-fuels is hydrogen (H2). Accurate chemical kinetic models are needed that can describe the combustion of fuel mixtu...

A possible solution to improve the combustion properties of ammonia is to blend it with other fuels. Two of the most usually used co-fuels are hydrogen and syngas (H2/CO). To investigate the chemistry of the co-combustion with these fuels, a large amount of indirect experimental data for the combustion of neat NH3, and NH3/H2 and NH3/syngas fuel mi...

In the last two years, three comprehensive reaction mechanisms were published, which can be used to simulate NOx formation during syngas combustion. The aim of this work is to investigate the performances of these mechanisms at various experimental conditions. The mechanisms of Zhang et al. and Glarborg et al. provided somewhat better results than...
