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

  1. General properties of fluids.
  2. Fluid static (basic laws, hydrostatic law, Archimedes thrust, hydrostatic forces calculation on submerged structures).
  3. Fluid cinematics (Lagrangian and Eulerian description of movement, permanent flow, mass and volume flow, particulate derivative, continuity equation).
  4. Incompressible perfect fluid dynamics (equations of Euler and Bernoulli, energy balance, height/loss of a motor/receiver machine, theorem of quantities of movement, applications).
  5. 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).
  6. Similarity of flow (similarity of two flows, Reynolds number).
  7. Flows into laminar and turbulent lines, medium load, singular and regular load losses.
