Abstract

Autoignition of nonpremixed turbulent mixtures undergoing a compression is studied by using DNS. The temporal evolution of the mean amount of heat released during ignition is used to distinguish between different ignition regimes. In particular, nonuniform distribution of mixture fraction dissipation rate along the stoichiometric line contributes to the development of partially premixed ignition fronts, in which the triple flame structure is observed.
