Abstract

Since turbulence is the most commonly observed form of fluid behavior, interest has been exceptional in the modeling of related phenomena. Beginning with G. I. Taylor’s seminal paper (Taylor (1921)), one school of study (Favre (1964)) has emphasized the statistical approach. A second major school of thought, following fundamental papers of Landau (1944), Hopf (1984), Lorenz (1963), and Ruelle and Takens (1971) uses Galerkin approximations to simplify the Navier-Stokes equations and bifurcation theory to analyze the resulting ordinary differential system (Barenblatt, Looss and Joseph (1983)). A more recent, computer-oriented approach is to solve the full Navier-Stokes equations numerically, assuming, of course, that these equations represent turbulent flow in some average sense (Markatos (1986)). In addition, there exists a variety of no less interesting, but less studied, approaches, as, for example, the thermodynamic model of Malkus (1960).
