Pollutant formation modelling in natural gas SI engines using a level set based flamelet model

Abstract: The level set flamelet model for turbulent premixed combustion was recently extended to improve the modelling of the spark ignition process, to incorporate the influence of unsteady flame kernel development on turbulent flame propagation, to embrace flame-wall interaction, and to comprise pollutant prediction models. The formation of nitrogen oxides (NO x) is predicted using the extended Zeldovich mechanism. The concentrations of the involved intermediate species are determined using a chemical equilibrium ass… Show more

“…The relationship of the presented parameters density, spatial dimension, and temperature to the influence parameter j is shown by its fundamental definition, independently derived by Bongiorno et al [71] and Yang et al [72], presented in Eq. (15). Usually, direct correlation functions, required in Eq.…”

“…The chemical reaction rate for each species is calculated in each time step as The GAMUT combustion model has been developed and implemented into the KIVA-3V code by Tan and Reitz [20,23]. It has been extensively used to simulate combustion in spark-ignited gasoline engines, in which the combustion process is a stratified premixed combustion [20,[23][24][25][26][27][28]. It has also successfully been applied to simulate diesel/natural-gas dual-fuel CI engines [29,30] and conventional diesel engines [30][31][32][33].…”
