Prerequisites

The prerequisite(s) for this Teaching Unit (Unité d’enseignement – UE) for the programmes/courses that offer this Teaching Unit are specified at the end of this sheet.
Main themes
  • Hydrostatics and floats
  • Flow models: perfect fluid, viscous fluid, turbulent fluid
  • Headlosses: major and minor losses
  • Hydrodynamic forces
  • Flow over weirs (introduction)
  • Design of water distribution systems
Content




1. Introduction. Hydraulics in Civil Engineering. Properties of liquids. Pressure.
2. Hydrostatics
  • Differential equations and integrals, manometers, resulting pressure forces
  • Theory of floats
3. Basic principles
  • Fundamental equations, Lagrangian and Eulerian approaches
  • Displacements, deformation and rotations
4. Flow models :
  • Perfect fluid
             - Kinematics of irrotational flows: stream lines and velocity potential, application of complex variables, conformal mapping, applications to the flow around bridge piers in rivers, to weir flows and to hydrodynamic profiles
             - Dynamics: Euler equation, integral equations of Lagrange and Bernoulli
  • Laminar flow
             - Constitutive equation for Newtonian fluid (Stokes assumptions) and Navier-Stokes equations
             - Steady laminar flow in pipes: parabolic velocity profile and discharge integral (Poiseuille)
  • Turbulent flow
             - Turbulence : statistical approach, Reynolds analogy, Navier-Stokes-Reynolds-Boussinesq equations, velocity profile (smooth and rough boundaries)
             - Headlosses : eddy losses (Darcy, Moody-Nikuradse) and minor losses
5. Applications
  • Liquid-sold interactions, hydrodynamic forces
  • Orifices and weirs
  • Pressurized flow in pipes and water distribution networks (steady flow) 
              - Simple pipes
              - Branched networks
              - Meshed networks (Hardy-Cross) and nodal methods (Newton-   Raphson)

Teaching methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

The activities are organised as follows:
  • Lectures for the main theoretical topics
  • Practical exercises on the different chapters; laboratory work (floats and pipes); small project work on the calculation of a water distribution network
Evaluation methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

Continuous evaluation based on laboratories, projects and a written test about the exercises.
Oral exam for the theoretical part.
Online resources
Moodle website where different resources are made available : PowerPoint slides used for the lectures, videos, partial lecture notes, exercises with solutions, other useful documents (practical information about the exercises, schedule of the activities, ...)
