Synopsis

The basic equations of fluid dynamics; Cartesian tensors, the viscous stress tensor; equations of state; linearisation, sound and internal gravity waves; phase and group velocity; non-linear evolution; shocks; computational methods; exact solutions of the full equations: plane Poiseuille flow, impulsively started plate; overview of numerical methods and analog experiments, dimensional analysis, scaling; low Reynolds number flow: properties, flow around a sphere, Hele-Shaw flow, Saffman-Taylor instability, viscous gravity currents; high Reynolds number flows; Bernoulli's Theorem and streamlines, vorticity and the vorticity equation, line vortices, circulation and Kelvin's theorem, potential flow; boundary layers: flow past a flat plate, flow past bluff bodies and separation.

Outcomes

On completion of this unit students should be able to:

  1. Explain the scope of fluid dynamics in the physical sciences;
  2. Summarise the derivation of the equations of fluid motion, including manipulating Cartesian tensors;
  3. Solve those equations in simple situations for compressible and incompressible flows, and simplify those equations using the methods of linearization, dimensional analysis and scaling;
  4. Explain the dynamics of linear waves in fluids, the physical reasons why waves may form shocks, and the nature of the developed shocks after they do;
  5. Summarise the properties of the Stokes equations for low Reynolds number flows;
  6. Apply Bernoulli's theorem to simple problems;
  7. Explain the concept of vorticity, apply that to irrotational flows and appreciate the role of boundary layers.
