✦ Synopsis

A prediction model for turbulent diffusion flames is presented and applied to H2-air-diffusion flames and in particular to the calculation of mean radical concentrations. The fast shuffle reactions in the H2-ah'reaction system are assumed to be in partial equilibrium, whereas the three-body recombination reactions are treated kinetically. These assumptions lead to a two variable formalism which allows the calculation of nonequilibrium values of radicals. It is shown that these values differ considerably from calculations obtained with equilibrium assumptions. The results of the calculations compare favourably with measurements of mean OH concentrations by .
