This module provides an introduction to fluid dynamics, and addresses the underlying physics behind many everyday flows that we see around us. It starts from a derivation of the equations of hydrodynamics and introduces the concept of vorticity and the essentials of vorticity dynamics. The influence of viscosity and the formation of boundary layers is described with some straightforward examples. The effect of the compressibility of a fluid is introduced and applied to shock formation and to the conservation relations that describe flows through shocks. A simple treatment of waves and instabilities then allows a comparison between theory and readily-observed structures in clouds, rivers and shorelines.

By the end of the module students will have an understanding of the physics of fluid flow as presented in the lectures and will be able to:
Introduction of Lagrangian and Eulerian derivatives. Derivation of the vector form of the equations of conservation of mass, momentum and energy. Brief review of simple equations of state. Introduction of the concept of vorticity and the essentials of vorticity dynamics. Bernoulli's equation with simple examples. De Laval nozzle flow and transition to supersonic flow. Basic introduction to viscosity and its importance in boundary layers. Reynolds number. Sound waves and formation of shocks. Conservation relations. Simple treatment of instabilities (convection, Rayleigh-Taylor, Kelvin-Helmholtz).
This module may not contain material that is part of the IOP “Core of Physics”, but does contribute to the wider and deeper learning expected in an accredited degree programme. The skills developed in this module, and others, contribute towards the requirements of the IOP “Graduate Skill Base”.
