Learning objectives
- Know the basic laws governing incompressible viscous fluid flows, associated assumptions, and classical examples of application (venturi effect, Toricelli formula, impulse of a jet...).
- Apply these laws to pipe flows with motor/receiver machines to optimize the circuit from the energy point of view.

Program
- General properties of fluids.
- Fluid static (basic laws, hydrostatic law, Archimedes thrust, hydrostatic forces calculation on submerged structures).
- Fluid cinematics (Lagrangian and Eulerian description of movement, permanent flow, mass and volume flow, particulate derivative, continuity equation).
- Incompressible perfect fluid dynamics (equations of Euler and Bernoulli, energy balance, height/loss of a motor/receiver machine, theorem of quantities of movement, applications).
- Dynamics of viscous fluids (viscosities and their measurements, tensors of deformation rates and stresses of a viscous fluid, laws of behaviour, equations of Navier-Stokes).
- Similarity of flow (similarity of two flows, Reynolds number).
- Flows into laminar and turbulent lines, medium load, singular and regular load losses.
Assessment
- Continuous checks
- TP reports
- Final review
