Main themes - Hydrostatics - Basic equations and flow models - Orifices et weirs - Pressure pipes
Aims - Initiation to hydraulics fundaments from continuous mediums mechanics - Theoretical and practical approaches of major problems of pressure flows pipes
Content - Introduction : domains of involvement of hydraulics, liquid properties, fundamental theorem about pressure (2 hours); - Hydrostatics (4 hours) : * Differential and integral equations, * Manometers, * Force component and centre of pressure on plane areas and curved surfaces, * Statics and dynamics of submerged and floating bodies; - Basic equations of hydraulics (2 hours) : Lagrangian et Eulerian approaches, displacement, deformation and rotation; - Flow model : * Perfect-liquid model (5 hours) : kinématics of irrotational flows : streamlines and potential, complex potential, conformal transformations; applications to bridge piers in rivers, to weirs and to hydrodynamic profiles, dynamics : Euler's equations, integral forms of Lagrange and Bernoulli; * Viscous-liquid model (2 hours) : Stokes assumption and Navier-Stokes equations, laminar in pipes : velocity parabolic distribution and discharge integral (Poiseuille); * Turbulent-liquid model (8 hours) : turbulence : statistical approach, Reynolds analogy, Navier-Stokes-Reynolds-Boussinesq equations, mixing length (Prandtl) velocity logarithmic distribution (smooth and rough turbulent cases), head losses : dynamic similitude, friction losses in pipes (Darcy, Moody-Nikuradse), eddy losses; * Application field of the models and selection of modelling assumptions - Applications * Liquid-wall interactions (2 hours) Hydrodynamic forces, Boundary layer; * Orifices et weirs (2 hours) * Closed conduits and pipe networks : steady flow (3 hours) : simple pipes; branching pipes; networks of pipes : mesh method (Hardy-Cross).
