This is a reading course in the dynamics of incompressible Newtonian fluids. We begin without viscosity and then go on to consider slow and fast viscous flows. There is a weekly problem sheet and some kind of recommended reading to go with it.

General details of the course are available here.

My syllabus and typed notes borrow heavily from lectures given by Keith Moffatt and typed notes produced by Michael McIntyre (MEM) for the second and third year Cambridge courses in Fluid Dynamics. Of course, any errors are entirely my own contribution.

HEALTH WARNING The notes and problem sheets below are the first versions. They contain typos and errors which were corrected verbally, but which may well not yet be corrected in the TeX files.

So far the contents are roughly as follows:

Week 1: Problem Sheet 1. Discussion on Monday 15 February.

This sheet provides
