Case of generation of turbulence injected at a fixed wavenumberThis title provides the fundamental bases for developing turbulence models on rational grounds. The main different methods of approach are considered, ranging from statistical modelling at various degrees of complexity to numerical simulations of turbulence. Each of these various methods has its own specific performances and limitations, which appear to be complementary rather than competitive. After a discussion of the basic concepts, mathematical tools and methods for closure, the book considers second order closure models. Emphasis is placed upon this approach because it embodies potentialsISTETurbulenceMathematical modelsFluid dynamicsTurbulenceMathematical models.Fluid dynamics.532/.0527015118Schiestel Roland1838674MiAaPQMiAaPQMiAaPQBOOK9911020087103321Modeling and simulation of turbulent flows4417711UNINA
