This module covers:
  • Fundamentals: historical perspectives, fluid properties, concept of pressure
  • fluid statics: force on submerged surfaces, buoyancy
  • concepts in fluid flow behaviour:
    • motion of a fluid particle, mass continuity, laminar and turbulent flow
    • momentum equation, Navier Stokes equations for simple 2D fluid flow
    • turbulence and the time averaged equations
    • steady flow energy equation and its application
    • applications of the momentum equation to the impingement of a jet on a surface
    • application to simple wind turbine theory
  • boundary-layer theory and applications:
    • velocity profile, skin friction and form drag, dimensionless groups
    • pipe flow networks, frictional resistance of moving bodies, lift and drag on aerofoil sections
  • potential flow: stream lines and the stream function for various simple flows (and combinations), the Kutta Joukowski law
  • compressible flow: 
    • isentropic flow behaviour, total and static quantities, the speed of sound
    • normal shock wave theory
    • flow in a convergent-divergent nozzle, compressible flow in a uniform duct with friction, isothermal flow with friction, compressible flow with heat transfer
  • flow-measuring devices
  • bulk flow:
    • Venturi meter, orifice plate, rotameter, vortex and turbine flowmeters
    • Point measurement: Pitot static tube, hot wire, LDA and PIV.
