Combustion, Modeling, Pulsed Flame Jet Ignition ABSTRACT This paper describes the combustion mechanism of a lean mixture ignited by pulsed flame jet ignition, based on an analysis done with a multi-dimensional combustion model. In order to apply a combustion model over a wide range of combustion regimes, from wrinkled flamelets to that of a well-stirred reactor, it is necessary to thoroughly understand the different combustion regimes. A novel time-scale interaction (TI) combustion model has been developed for simulating combustion phenomena with high accuracy. The TI combustion model applies two different combustion models to suitably match the combustion mode in a pulsed flame jet, by factoring the characteristic time scales of the chemical reactions and turbulent mixing into the scope of application of each model. The TI combustion model was applied to the combustion mechanism in a constant-volume vessel. The results show good agreement between the experimentally obtained schlieren photographs and the calculated temperature iso-surfaces during the combustion process.
