Course content:
This graduate course is intended to cover the most important issues related to physical understanding and modeling of turbulent flows. The subjects to be addressed are the following: Review of the equations of motion and typical turbulent flows. Hydrodynamic stability and transition to turbulence. Reynolds averaging and the closure problem. Isotropic turbulence. Navier-Stokes equations in Fourier space and statistical theories. Vorticity dynamics, intermittency and cascade models. Scaling and self-preservation in boundary-free and wall-bounded shear flows. Transport of scalars and turbulence in compressible flows. Turbulence modeling for computational fluid dynamics: one-and two-equation models of extensive use in engineering applications, Reynolds stress models, pdf methods, direct-numerical and large-eddy simulations. An overview will be given of modern developments in turbulence theory: renormalization-group theory, chaos, fractals, etc..
