Hydrogen jet flame ignition technology, based on active pre-chamber, is an effective approach to improve the combustion inertness of ammonia. Revealing transition mechanism ammonia diffusion ignited by hydrogen flame, driven coupling chemical reactions and mass transfer, great significance for developing advanced strategies. This paper offers a comprehensive analytical perspective development process ammonia–hydrogen combustion. The results show that, compared with pre-chamber structure, direction has more significant impact turbulence kinetic energy mixture. slender throat structure intensifies turbulent thermal dissipation effect, which detrimental formation propagation initial flame. can be divided into four stages. squeezed main chamber during mixture stage significantly impacts speed During from shifts its dominant factor transfer rate reaction rate. initially focuses thin zone, followed front becoming corrugated under influence vortices study provides important theoretical basis strategies, especially in context as power sources zero-carbon marine vessels.
