Learning Outcomes

After completing this paper students are expected to:

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