After completing this paper students are expected to have achieved the following major learning objectives:

  • Know the difference between Lagrangian and Eulerian frames of reference in the description of the movement of fluids;
  • Understand the conservation of mass, momentum and energy in fluid flow, leading to the derivation of the Navier-Stokes equations;
  • Be able to approximate and manipulate the Navier-Stokes equations into forms suitable for particular situations;
  • Understand some fundamental theorems of fluids, e.g. Kelvin’s circulation theorem;
  • Understand the implications of space and time for the equations governing boundary layer flow;
  • Apply the equations governing basic wave motion in fluids;
  • Derive equations for the growth/decay of linear perturbations in a simple flow;
  • Be able to outline how small perturbations evolve to fully developed turbulence;
  • Understand the arguments introduced in a basic quantification of turbulence.

Topics:

  • Flow of ideal fluids & kinematics & conservation laws
  • Viscous fluids, dimensionless numbers and similarity
  • Waves & instabilities
  • Turbulence
  • Boundary layer flow
  • Convective transport
