New experimental data on laminar flame speed to improve ammonia kinetic mechanisms

Résumé

This study focuses on the role of ammonia (NH3) as a promising hydrogen carrier and a carbon free fuel for future energy production, marine transport, and industrial processes. To enable the implementation of ammonia as a fuel, accurate kinetic mechanisms for ammonia oxidation and pollutant formation are crucial, necessitating numerical simulations. To improve these mechanisms, new experimental data for laminar flame speed (SL) under various conditions were obtained. The results, including the impact of hydrogen addition, were compared with existing kinetic mechanisms and literature data. While most mechanisms gave good predictions of SL as a function of equivalence ratio, discrepancies were observed for rich and lean mixtures with lower hydrogen content. No mechanism perfectly captured SL as a function of hydrogen content and equivalence ratio, indicating the need for further refinement and validation.
