Sinopsis

For new generation highly downsized spark ignition engines, the proportion of fuel which is consumed near the wall increases significantly. It is therefore necessary to model accurately the flame / wall interactions. While current models take into account the effect of the wall on the flame, the effect of the turbulent flame-wall interaction on the wall heat flux is still lacking. A model, based on the flame surface density concept, is proposed in the present study in order to take into account this effect. It attempts to evaluate the proportion of the flame in the computational cell that interacts with the wall as the quenching distance is reached. A first validation of the new wall model is presented using DNS data of a 2D V-flame.
