Turbulent mixing and flame stability in a dual-swirler ammonia/methane co-flame burner : Reynolds number effects on NOx emissions
An innovative coaxial dual-swirl combustor was developed to address the challenges of combustion instability and NOx emissions inherent to ammonia combustion. The combustor employs an inner swirler supplying a premixed ammonia/air stream and an outer swirler generating a premixed methane/air flame that stabilizes the inner ammonia flame. Combined large-eddy simulations (LES) and planar laser-induc
