Abstract
Specifics of nitrogen oxides formation in conditions of partially mixed combustion in combustion chambers in the presence of diffusion and homogeneous flame fronts are studied. A NOx emission calculation procedure based on detailed kinetics, including all NOx formation mechanisms, is proposed. NOx emission values calculated using the complete detailed kinetics and kinetics containing only the Zel’dovich mechanism are compared. A methodology for estimating the effect of homogeneous flame fronts on NOx emission is proposed and verified. Under conditions of the model problem, a contribution of homogeneous flame fronts to total NOx emission is studied. Combustion conditions with a considerable contribution of homogeneous fronts to total NOx emission are shown.
