Fluid Dynamics and Waves: Flow-induced forces and circulation - 2nd Year Student Lecture
Вставка
- Опубліковано 13 кві 2024
- Having derived Blasius’ Theorem, in this lecture from his second year 'Fluid Dynamics and Waves' course, Dominic Vella (re)-considers flow past a cylinder and confirms D’Alembert’s paradox that simple flow past a cylinder leads to no drag force. He also shows how the presence of circulation around the cylinder leads to a lift force (though still no drag). The sign of this force is different than would be predicted based on a simple molecular picture of fluid flow, and shows a continuum effect.

All first and second year lectures are followed by tutorials where students meet their tutor in pairs to go through the lecture and associated problem sheet and to talk and think more about the maths. Third and fourth year lectures are followed by classes.
Keep uploading the physics and mathematics content consistently. You are doing a great help by uploading the lectures on You Tube. Thank you.
this lecture's board(and also the lecturer) is much better than that of the MIT opencourses' 😁😁
Niggae,

Bernoulli’s principle….
Hell, that kind of shit was going in this morning.
I am NOT a faggot.
Especially for the entity passing into the garage this morning, exhibited gaseous effects in a way that can considered archetypal.
Let’s just not bring up bernoulli’s principle: that’s a properly electro-magnetic effect.
Not this, you know, ….
I mean one perturbs about the car vibrations in the morning
Absolutely not the same thing as bernoulli’s principle *proper*
Sir which board are you used ❓
He reminds me of the guy that stole my pipe in eureka, california.
#PIPEOFWHAT
We got that steel ball in a pot
#GLYCERINE
I wonder how a zero g environment would affect things.
I tried explaining this to my boss

Andy Nguyen, a fluid dynamicist.
Not to be confused with
Andy Wathen, one of the great numerical fluid dynamicists of our era,
and
Irene Moroz, one of the great qualitative nonmathematical holomorphic observers of our era.
A beautiful counterpart to the theory of differential forms:
WHAT IS dz here? What is its ‘reflection’ dz bar: the 4-fold prerequisite one uses to integrate over an elliptic curve (Torus) embedded in 3 space:
In particular, there is a question of dimension.
If the relativistic (Reynolds) volume integrals are 3 forms
Elementary calculus concerns itself with 1-forms.
What is dz? A 2 - form or a 1 - form.
As a personal practice, I’m reminded of the line from Eminem, another great observer of truly very serious but not archetypally irrelevant dynamics
‘You look insanely whack when just a FRACTION of my tracks run’
dz, though used in something to give a different aesthetic attempt at capturing the ‘work’ or ‘circulation’ concept - and therefore interpreted as a 1- form,
Is most obviously understood as a 2-form: is that not what the complex numbers are defined as being even in an algebraic setting?
Lectures will follow from here.
Hello sir
You How much salary does he get?
Sir which class is this?
