### 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; Bernoulli's equation; vorticity and circulation; Kelvin's circulation theorem; rotational and irrotational flow; two dimensional homogenous incompressible flow; viscous effects and boundary layers; separation from a ball, with applications to cricket, golf and baseball; flow in a rotating reference frame, geostrophic flow.

### Outcomes

On completion of this unit students will be able to:

1. Understand the scope of fluid dynamics in the physical sciences;

1. Apply the method of linearisation, and apply it to the dynamics of waves in fluids;

1. Understand the physical reasons why waves may shock, and the nature of the developed shocks after they do;

1. Appreciate blast wave solutions, and the method of similarity;

1. Use several basic numerical methods for one dimensional gas dynamics, and understand their strengths and limitations;

1. Understand how the fluid equations can be simplified for inviscid incompressible flow;

1. Calculate some simple irrotational flows;

1. Understand the effects of viscosity on high-speed flow, including the formation and behaviour of boundary layers;

1. Appreciate the properties of rotating flows and the importance of the geostrophic approximation to flows on the surface of the Earth.
