Course description
Credit points: 3
Prerequisites: 0542.4320- Mechanics of Fluids (2)
Basic definitions, Navier-Stokes equations, viscosity, transition to turbulence, state-of-the-art experimental methods in turbulence. Length scales, time scales in turbulent flows. “Eddy-viscosity”, turbulent diffusion, limitations of the mixing-length models. Basic statistical tools, correlation, spectrum, co-spectrum. Kolmogorov theory. Dynamics of turbulent transport – Reynolds decomposition, kinetic energy, Reynolds stresses, closure problem, dissipation and pressure. Scalar transport in turbulent flows. Homogeneous turbulence. Shear turbulent flows: wakes, jets, boundary layers. Modeling of turbulent flows, turbulent models, and numerical simulations.
