Flame Modelling of Premixed Ammonia Combustion in Swirl Burner using LES

Abstract

The objective of the LES simulation is to investigate how operational parameters affect flame properties in combustion of the premixed NH3/H2/air inside a swirling burner. Key parameters explored include the differential blend ratio of NH3/H2 fuels, ignition conditions, flow dynamics, and the balance between accuracy and computational cost using reduced chemical kinetic mechanisms. The numerical simulation findings suggest optimal operational conditions for enhancing thermal efficiency and controlling NOx emissions for experimental setups, scaling up combustion platforms.
