Flame dynamics and chemical kinetics analysis of premixed methane-hydrogen-air blends in variable cross-section pipes

Key Points

• Flame dynamics are influenced by the varying composition of methane-hydrogen blends, affecting combustion stability.
• Chemical kinetics show significant differences at various cross-sectional areas of pipes, impacting reaction rates.
• Assessment using premixed blends in variable cross-section pipes demonstrates critical mass transfer effects during combustion.
• These findings highlight the need for optimizing flame behavior in energy systems relying on hydrogen-enriched fuels.
