30% and 45%, exceeding results at 15% and 60% by 14.6% and 6.3%, respectively. The 30% condition also achieved the peak
flame area in the shortest time, at 8.2 ms. Furthermore, geometric constraints at the junction of the cylindrical sidewall and the
endwall led to accumulation of unburned hydrogen, causing localized increases in density and pressure and resulting in four
clearly discernible high-velocity regions within the flow field. At 9 ms, the flow velocity profile along the centerline exhibited
symmetry with a dual-peak structure appearing unilaterally. While the 45% condition showed an early transient velocity
advantage due to intensified local heat release, the 30% condition demonstrated superior late-stage velocity recovery owing to
more stable and sustained combustion near the stoichiometric ratio. These findings underscore the high combustion efficiency
and stability achievable near stoichiometric conditions, providing a scientific foundation for the design and optimization of
high-efficiency hydrogen combustion systems.
