FTP, name this phenomenon that takes place in fluids with large Reynolds number, and is characterized by the formation of eddies and vortices.
A Markovian theory of this phenomenon is called EDQNM, while an equation governing this describes the longitudinal velocity correlation, and is called the Karman-Howarth equation.  The Klebanoff intermittency function appears in the Cebeci-Smith model of this, and another model is the Baldwin-Lomax. Analysis of this phenomenon sometimes makes use of the Boussinesq approximation, and the smallest length-scale on which it can occur is named after Kolmogorov. It is often analyzed with the Reynolds-averaged Navier- Stokes equations, and can be studied with chaos theory.
