A Unified Model of Mean Reaction Rate in Turbulent Premixed Flames

We developed a model of the mean reaction rate in a turbulent premixed flame to predict time-averaged profiles of the velocity, temperature and species concentrations in practical combustion systems. The fundamental features of the model consists of chemistry- and mixing-controlled reaction rates which vary with the local Damkohler number. The comparison of numerical predictions with experiments demonstrated the applicability of the concept to the flames of wide range of Damkohler number.
