Sažetak
Ammonia represents an alternative carbon-free fuel and a possible solution towards transition to a low carbon economy. In this work, simulation of ammonia combustion in an experimental premixed swirl burner has been conducted, where the effect of different turbulence models on physical value fields, as well as species concentrations at the domain outlet was analysed. Application of various turbulence models, namely k-epsilon, k-zeta-f, LES, has shown satisfactory agreement to experimental measurements. Predicted NO concentrations were matched with experimental data for the case nearest to stoichiometric conditions, especially in the case of k-zeta-f and LES models. There is still need for furter investiagation and improvement of carbon chemistry. This work contributes to the extension of current knowledge of ammonia combustion at operating conditions closely resembling those in industrial plants and it is expected that obtained findings from this work will help in future analysis while designing real industrial systems for ammonia combustion.
