The equation for correlation function of a scalar field, closed by suggested relation between the third and the second order two-point moments, is used for calculating the evolution of spherical volume of a passive reactive scalar. Correlations are described by the Corrsin equation with additional terms arising due to non-homogeneity and reactivity of scalar field. Together with the equation for the correlations, the equation for the probability density distribution of a passive scalar was needed for the mean chemical reaction rate calculation is used. The feature of this approach is the separation of influences imposed to micromixing by turbulent velocity and molecular transfer. The compatible calculation equations were used enables one to determine the evolution of the turbulent diffusivity, and the scalar dissipation, and the reaction wave rate regularities.
Mots-clés : turbulence, turbulent combustion.
