* 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;
