RÉSUMÉ
A new ignition/combustion model for explicit flame tracking has been developed and tested against various internal combustion (IC) engines and operation conditions. The model is physically grounded and contains only one fitting constant with a default value of unity. The model is based on the understanding that turbulent flame evolution involves two major stages: initial and regular. Combustion at the initial stage is mostly governed by local physicochemical properties of the reactive mixture and by small-scale turbulence, whereas combustion at the regular stage is largely governed by large-scale turbulence.
