About course

The turbulence in fluids is a phenomenon of fundamental importance in physics, but extremely difficult to interpret and explain. The understanding of turbulent flows is needed in the analysis of many engineering problems, such as aerodynamics of airplanes and automobiles, efficiency of internal combustion engines, optimization of wind turbines, weather forecasting and dispersion of pollutants in the atmosphere. The discipline "Modeling of Turbulent Flows" discusses the characterization of turbulence, the theory developed over the years for its description and key strategies for the modeling. Among the models detailed in the discipline, we highlight the direct numerical simulation (DNS), large-scale simulation (LES) and with emphasis, eddy viscosity models and models of transport of Reynolds stresses.
