Extinction limits and structure of counterflow nonpremixed methane-ammonia/air flames

An experimental and computational investigation on the fundamental combustion characteristics of methane (CH4)-ammonia (NH3) blends is conducted to confirm their potential as a clean fuel with low carbon dioxide (CO2) emissions and determine their reasonable burning conditions, considering counterflow nonpremixed CH4NH3/air flames. Extinction limits and structure of the nonpremixed CH4NH3/air flames are measured and predicted. Results show that...
