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 dynamicsElectronic books.TurbulenceMathematical models.Fluid dynamics.532.0527015118532/.0527015118Schiestel Roland920429MiAaPQMiAaPQMiAaPQBOOK9910139486703321Modeling and simulation of turbulent flows2064448UNINA02076oam 2200673 450 991069265090332120210216110906.0(CKB)5470000002354956(OCoLC)680243774(OCoLC)631643775(OCoLC)667882347(OCoLC)974646886(OCoLC)1153330018(OCoLC)995470000002354956(EXLCZ)99547000000235495620101110d1990 ua 0engurbn|||||||||txtrdacontentcrdamediacrrdacarrierLarge springs in the Valley and Ridge Province in Tennessee /by E.F.
