| Abstract: | The accuracy of the method of calculating turbulent reacting flows [1–3] which is based on the use of the conditional mean concentrations of the reacting components is analyzed. The effect of large-scale fluctuations of the dissipation of passive admixture concentration [4–6] on the accuracy of the equations for the conditional means is considered and the corresponding corrections are computed. By means of numerical calculations the models for the conditional moment and traditional calculation methods are compared, as are the various approaches to the computation of the coefficients of the equations for the conditional means.Translated from Izvestiya Rossiiskoi Akademii Nauk, Mekhanika Zhidkosti i Gaza, No. 5, pp. 50–59, September–October, 1993.The author wishes to express his wann thanks to A.
