Fluid Dynamics 3 - 2020/2021


Organisation


Lecture notes

A complete set of reference notes is provided in advance of the course from the link below. The lectures will cover this material perhaps not identically nor in chronological order. The emphasis in lectures will be explaining how to think about problems in fluid dynamics and how the material relates to real-life physical applications. This is really important for this unit where a lot of mathematicians struggle in exams to turn the question about the physical problem into mathematical equations.

Here is some supporting material:


Course delivery

Recordings of my lectures will be made in my zoom room (with links to mediasite videos added once recordings complete) at the following times:

Q: cheeky q - any hints for what's on the exam?
A: here's an advance copy

Comment: Since taking this course I can no longer watch YouTube without constantly applying fluid dynamics knowledge to everything, and I love it... here's a cool one: https://youtu.be/k9oBTSIV8To
A: Arh ! A true disciple.

COMMENT: Just wanted to say your 2017 paper on cloaking in water waves was some really nice (if not rather challenging) subsequent reading to Chapter 8 - it's always great to see modern applications of the concepts we learn!
A: That's quite a big jump. Even I don't really understand it.

Q: I'm a few lectures behind, but for the purposes of planning my revision, is lecture 29 the last one, or will there still be more content in January?
A: Yes: read your emails, goto the end of lecture 29 where I write THE END or notice that Lecture 29 is the last topic in the notes. I will no doubt be giving some revision lectures in Jan.

Q: you mentioned you would try to cover q4 exam 2019 in todays problems class but you didnt have time for it, could you release model answers to it for if we get stuck please?
A: Yes. At some point. For now I think it's right that I provide you with some questions without having answers to fall back on. Cos that's what you'll face in an exam.

Q: this too shall pass is very cool, but you should watch this one moment by OK Go, I think its more impressive!
A: I hadn't seen that one, thanks. And it's got some fluid dynamics in there too. I'm still sticking with TTSP though ! I Won't let you down is mad too.

Q: The assessed homework date deadline stated on the webpage says Tues 25th Nov, but Tues is the 24th not the 25th
A: I'm really struggling with numbers this year

Q: When you record the live lectures and upload them, when I watch the replay I struggle to read the board idk maybe because of the lighting? It isn't very clear. Maybe you can repeat out loud what you are writing each time for us to write down if we can't read. Other than that, the course is very enjoyable and you explain everything perfectly. Thank you!!
A: Thanks for letting me know that the live sessions are difficult to follow on the board. I've been alerted to this a couple of times now. There is a lighting issue with later lectures after the clocks changed, the lack of natural light and the reliance on ceiling/board lights. I think I need to write larger and this will help; also the boards this week were really filthy. FWIW you might also want to follow the written solutions which should correlate to the board solutions. Because I have a live audience, I have to deliver the material with those people in mind primarily. It's quite a difficult compromise. I think I know enough of the problems to make it better in the future though. Thanks

Q: Thank you for the lectures so far they have been amazing! I was just wondering, with the addition of the reading week, does this mean that problem sheet 6 (the assessed one) will be pushed back a week until week 7 of the term? Or will it still be week 6? What would the set and due dates be?
A: Yes, everything is pushed back a week by the reading week. Assessed HW2: Set Tuesday 17th November to hand in Tuesday 24th November 10am Assessed HW3: Set Thursday 10th December to hand in Thursday 17th December 4pm.
And yes, I realise the last hand in is close to Xmas, but that's what happens if we fit in a reading week into an 11 week instead of 12 week term.

COMMENT: Thought you might appreciate this mega-sized vortex cannon (Disclaimer, this definitely wasn't found whilst procrastinating instead of doing the assessed homework...)
Holy smoke rings ! That's a biggun !

COMMENT: Lectures are wonderful so far, some of the best I've ever experienced at the uni. Your constant connections to physical settings makes the content easily digestible (which unfortunately is so often omitted by other lecturers), and the natural humour has really helped make the content memorable already (very excited for the future endeavours of the Trump household!). Your unit webpage also makes everything very clear, and the lecture recap summaries next to the hyperlinks are something every unit should adapt. Just wanted to say thank you for the clear enthusiasm you have for the subject, it makes it so much more enjoyable to learn and is actually quite inspirational! We're only 2 days into teaching and I can already tell this will be my favourite unit :D (Hope you can get a new kettle by the way)
REPLY: Thanks for this ! Always good to hear that students are enjoying the course. Remember, this is a joint effort... and you play your part in making the course enjoyable too.
