# PX264 - Physics of Fluids

• Module code: PX264
• Module name: Physics of Fluids
• Department: Physics
• Credit: 7.5

## Module content and teaching

###### Principal aims

The module should explain why PDEs (with associated boundary conditions) are an appropriate model for fluids. You should learn how physical ideas and limiting cases can help analyse these PDEs which, in general, cannot be solved. These include the role of the Reynolds number, laminar viscous flow, the boundary layer concept and irrotational flow. The module also prepares you for future applied mathematics modules.

###### Principal learning outcomes

At the end of the module you should be able to: Recognise and write down the equations of motion for incompressible fluids (the Navier- Stokes equations) and understand the origin and physical meaning of the various terms including the boundary conditions; Derive Poiseuille's formula and understand the conditions for it to be a valid description of fluid flow; Use dimensional analysis to analyse fluid flows. In particular, you should appreciate the relevance of the Reynolds number; Simplify the equations of motion in the case of incompressible irrotational flow and solve them for simple cases including vortices; Explain the boundary layer concept.

###### Other essential notes

The field of fluids is one of the richest and most easily appreciated in physics. Tidal waves, cloud formation and the weather generally are some of the more spectacular phenomena encountered in fluids. The module establishes the basic equations of motion for a fluid - the Navier-Stokes equations - and shows that in many cases they can yield simple and intuitively appealing explanations of fluid flows. The module concentrates on incompressible fluids.
