PEES7AE Turbulent flows
| ECTS Credits : 2 Duration : 21 hours | Semester : S7 | ||
Person(s) in charge : Dr. Hervé COMBEAU, Professor, herve.combeau@mines-nancy.univ-lorraine.fr | ||||
Keywords : Fluid Mechanics, turbulence | ||||
Prerequisites : Basic knowledge about laminar flows | ||||
Objective : Provide konwledge about turbulent flows | ||||
This course is the follow-up of the previous one about fluid dynamics. It introduces the concept of turbulent flow and the basics in turbulence. The model k-e, which is used quite often in the industry, is presented in such a way as to allow students to then move on to modeling. Content: • Characteristics of turbulent flows: Transition towards turbulence, random characteristics of spatio-temporal magnitudes, consequence of turbulence. • Semi-empirical turbulence models: Statistical approach, semi-empirical approach, k-e model. • Application to simple cases. • Turbulent boundary layer. • Flows around obstacles: Boundary layer detachment. Definition and calculation of drag forces and lift. Effects of turbulence on drag and lift forces.
