In this study, explosion characteristics with varying initial pressure and equivalence ratio were identified under the conditions of α=43% (40% NH3, 45% H2, and 15% N2), which are reported to be similar to the laminar flame properties of methane/air mixtures. The maximum explosion pressure (Pmax) and explosion index (KG) reached the maximum values at equivalence ratio of 1.1, while the explosion time (tc) reached its minimum at 1.1. Furthermore, it was observed that as the initial pressure increased, both the explosion pressure and explosion time increased.
