Module description
Fluid dynamics, the description of the motion of fluids, is an area of science that finds application across a wide range of scientific topics. The present module aims to provide a general introduction to the basic mathematical theory used in fluid dynamics as well as giving a more physical introduction to some common fluid flows of practical interest.

The module will commence with a general introduction to the general properties of fluids followed by a treatment of the basic governing conservation equations. Some examples of two-dimensional inviscid flows will be presented followed by the introduction of a discussion of the influence of viscosity. The effect of viscosity will be then included and the Navier Stokes equations derived. The origin and importance of some common flow instabilities will then be described together with an introduction to fluid turbulence. An introduction to compressible flows will also be given. All of the above will be supported by reference to examples of fluid flows in practice. These will include flows such as flows over aerofoils, magnetohydrodynamnics, atmospheric flows, pipe and jet flows and shock wave formation.

Learning outcomes
After taking this module students should be able to:

• have revised basic fluid properties and relevant thermodynamics.
• be familiar with the mathematical form of conservation equation for fluid flow.
• be able to solve simple two-dimensional flows.
• be familiar with the description and nature of flows where viscosity is not negligible.
• understand and be able to describe the origins of flow instabilities and fluid turbulence.
• be able to describe the influence of compressibility effects on fluid flows.

Students will have some opportunities to observe the use of computational fluid dynamics to simulate some fluid flows.
