Teaching Information

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

Lectures for HT24 are 10–11 on Mondays and 12–1 on Tuesdays in the Lindemann Lecture Theatre

The class will be 4–6pm on Tuesday of 5th week (13th February 2024) in the Lindemann Lecture Theatre.

Homework is due by 11:59pm on Friday of 4th week (9th February 2024). Please hand in work via the course page on Canvas.
In case of problems, please email a scan to the TA and cc to mmathphys@maths.ox.ac.uk

In HT24 Complex and non-Newtonian Fluids will be lectured first. Resources for this part of the course are here.
