Abstract
Based on the equation obtained earlier for the joint probability density function of the fluctuations of an isotropic turbulent scalar field of a reagent and its gradient[Inzh.-Fiz. Zh., 71, No. 5, 827–849 (1998)] the authors derived and numerically solved an equation for the specific isoscalar-surface area Σt(Γ) in a turbulent reactive flow. The equation for Σt(Γ) contains the single-point probability density function for pulsations of a reactive scalar and the time function that depend on the distribution of the energy of turbulent velocity pulsations and the intensity of scalar reagent pulsations by different length scales. The corresponding equations are written for all these functions.
