A model for calculating the probabilistic behavior gasdynamic variables of a jet undergoing physical and chemical transformation
Abstract
The paper suggests a statistical model of isobaric turbulent jets, allowing determination of the means, variances, longitudinal correlation coefficients and longitudinal scales in isothermal and nonisothermal turbulent jets and diffusion flames with physical and chemical conversions such as dissociation and ionization. It is assumed that turbulent mixing is a Markovtype process. KolmogorovFokkerPlanck equations are used for purposes of investigating the properties of twopoint probability densities of fluctuations of gasdynamic parameters and the aforementioned statistical characteristics are determined.
