Effects of swirl intensity on flame stability and NO emission in swirl-stabilized ammonia/methane combustion

open access: yesApplications in Energy and Combustion Science, 2023
Ammonia is an attractive clean fuel for its potential to reduce CO2 emission and fossil fuel consumption. However, ammonia combustion has been mainly discouraged by the low flammability and the high fuel NOx emissions. This study numerically investigates
