Effects of hydrogen enrichment on the autoignition and lift-off behavior of ammonia jet flames in hot coflows

Key Points

• Autoignition behavior improves with hydrogen enrichment, leading to better combustion efficiency.
• Lift-off heights decrease significantly by 30% when hydrogen is added in coflows.
• Analysis of ammonia jet flames in a hot coflow setup illustrates the impact of hydrogen on flame characteristics.
• This finding highlights the potential for hydrogen-enriched fuels to enhance combustion processes.
