Abstract:
A theory based on the probability density function of velocity difference, derived from the Navier-Stokes equations, is presented. The formally exact derivation leads to a pressure term and a dissipative term that need to be modeled. The asymptotic expression of the pressure term for large velocity differences can be derived using functional techniques, and a model valid for all the range of velocity differences can then be constructed. The asymptotic, large velocity difference range, of the dissipative term is modeled based on simple arguments applied to dissipative structures of Lundgren's type. Solutions of the resulting equation are studied in different types of asymptotic limits, and comparison with experimental probability distributions is made. © Elsevier, Paris.
