Abstract
The influence of chemical kinetics on the turbulent combustion of nonp remixed reactants is considered. Several tests of the flamelet model d eveloped earlier have been performed. Chemical and hydrodynamical calc ulations can be effectively decoupled using this model since it predic ts the dependence of temperature and reacting species concentration on ly on conserved scalar and scalar dissipation. Calculations of mean C( n)H(m), NO(x), OH, and CO concentrations and maximum flame temperature are found to be in satisfactory agreement with data obtained in jet d iffusion flames. It is found that the influence of finite rate of chem ical reaction is significant even in cases far from the flame extincti on. Limitations of the model are discussed.
