The book is carefully divided into three main parts: - The design of mathematical models of physical fluid flow;- A theoretical treatment of the equations representing the model, as Navier-Stokes, Euler, and boundary layer equations, models of turbulence, in order to gain qualitative asFluid dynamicsMathematical modelsFluid mechanicsFluid dynamicsMathematical models.Fluid mechanics.532.5015118Ansorge R(Rainer),1931-294988Sonar Th(Thomas)767915MiAaPQMiAaPQMiAaPQBOOK9910841795703321Mathematical models of fluid dynamics4136046UNINA
