Statistical Methods in Reacting Turbulent Flows
Modern combustion theory often finds it necessary to take into account fluctuations in velocity, composition and thermodynamic state variables of a reacting flow system. Methods for doing this have been intensively explored, especially over the past decade. It has been found that reactive flows pose exceptionally difficult problems for moment methods of analysis. The alternative of a probability density function description is now developed sufficiently for its potential to be assessed. The possibilities of a mixed description, partially by moment formulation and partially by probability density functions, have also been explored.
