Teaching Information

Lecture notes (last updated 16th January 2023) and problem sheet for Part 1 of MMathPhys Advanced Fluid Dynamics (course page)

Lectures for HT23 are 10–11 on Mondays and 12–1 on Tuesdays in the Lindemann Lecture Theatre

The class will be 4:30–6:30 on Monday of 5th week (13th February) in the Lindemann Lecture Theatre.
Homework is due by 10am on Wednesday of 4th week (8th February). Please hand in work by email to the TA, Michael Nastac <michael.nastac@physics.ox.ac.uk> with a cc to <mathematical.physics@maths.ox.ac.uk>

In HT23 Complex and non-Newtonian Fluids will be lectured first. Resources for this part of course are here.
