Flame dynamics and kinetic coupling of ammonia and dimethyl-ether in non-premixed cool and warm flames at elevated pressure

Key Points

• Kinetic coupling of ammonia and dimethyl-ether significantly affects flame dynamics under elevated pressure.
• In experiments, cool and warm flame behaviors were differentiated based on their temperature gradients.
• Assessment using experimental flame studies demonstrated variations in combustion characteristics.
• The findings may enable improved combustion system designs, emphasizing the need for further investigations.
