Introduction- definition of turbulence, history, characteristics.

Flow kinematics - dynamical system (Lorenz model), Cellular Automata Model, kinetic theory, continuum.

Statistical description of turbulence, Reynolds conditions, equations of motion, continuity equation - shallow water approximation, closure problem, higher order correlation tensor, theory of turbulence.

Homogeneous and isotropic turbulence - characteristics, correlation tensor, equations of motion.

Turbulent diffusion - Lagrangian analysis

Turbulence models - algebraic (Prandtl´s momentum transfer theory, Taylor's vorticity transport theory, Von Kármán´s similarity hypothesis) one-point turbulence models (k-? model)
