Fluid Mechanics - flow around cylinder

[plmihbyfcrszw]

This sounds like the song inside the Peach's Castle in Super Mario 64.

[worseize]

Please tell me what song is it ?

[1996amitC]

thumbs up if you thought it was a blackhole by just watching the thumbnail

[TMVector]

Looks like a knot in wood grain

[josyula547]

Thank you very much for upload

[flashkillerffff]

1 thought about the music

2 girls one cylinder

[SouthNJPC]

@flashkillerffff

Don't know if i find that funny as hell or just disturbing you are thing about and referencing that video!!

[flashkillerffff]

@SouthNJPC its the same music.

[airlinerdude12]

of course this is not in real life. As in a sense of how fast the fluid is moving

there are many "eddies" around a sphere at high speeds.

[Shift4chizzle]

is that in space

[engahmedsalah]

oooooooooh!!! nice work yeah will done

[HeavyDemir]

is this in a program or in water

[elninotsonat]

Nice video. Maybe you also want to watch a stone skipping video in ultra slow motion:

Stone skipping in ultra slow motion (HD).

[sobeita]

Can you possibly direct us to a page that shows the laws behind this?

[lolzordje123]

@sobeita search for bernoulli in wikipedia

[Setcs]

unless you trip it, turbulence won't occur until Re exceeds about 200,000.

[Setcs]

sigh @ these comments...

[Setcs]

sigh

[jjjohnson1232]

Uh i dont think this is a real computer simulation lmao

[superhornet59]

actually this is pretty stupid.. no turbulance in the back? man come on..

[TheMatrixHasYou38]

The turbulence occurs if you bring a certain amount of energy to your system.

If the speed of the fluid is slow, you are in laminar conditions, means no turbulence.

So before saying this is stupid, review your basis in physics!

[DJohnny79]

@TheMatrixHasYou38

Na c´mon, this is a little more than "basics in physics" i guess ;-)

But you´re right, as far as i remember it gets turbular from a Re>2300, right?

[jimmayl1]

If I remember right, its laminar up until ~1000, periodic laminar up to ~2000 and turbulent after.

[DJohnny79]

@superhornet59

there ARE some turbulences behind the cylinder, even though they don´t have to be there, as long as you keep the speed low enugh (Reynolds Number)

[superhornet59]

no the other guy is pretty right, serious turbulance will occur once the fluids energy is high enough to cause flow separation. yeah 'technically' there's always some turbulence because its a non ideal fluid flowing around a surface with small imperfections.

but that's just an excuse. I was still wrong. Kudos to the other guy, he made an excellent point.

[transform982002]

i know it sounds crazy but i'm pretty interested in the background music, any ideas ?

[11Will1]

trippy

[SVnerd]

Just a question, is the fluid lighting up because of a laser and is this considered to be PIV (Partical Image Velocimetery)?

[ChemicalComedown]

Excellent work . . .

[ultimatecrayon]

whats the song?? !

[Jenjoliveur]

Is this finite elements ?

[Yassoua]

intellectual masturbation, CFD people like that

[e2kk]

lol, very true

[parkouryo]

this is just the way fluid behaves arround a two-dimensionnal object (a circle en this case). I would like to know what coding language was used to get this simulation.

[appelstijl]

It's real, not a computer simulation

[ariosona]

Check the comment actually left by the person who posted the video..."this video on fluid mechanics was conducted by computer simulation."

[ImpossibleIsNth]

This simulation if for an ideal fluid.

Not possible to be real.

[SobeDragon7]

ooh pretty streamlines

[mattolika]

*doctor who theme*

[anne2matthew]

It looks like a supernatural things... awesome

[GaL4GoD]

oh well that makes it quite a bit awesomer, now doesnt it? XD

[GaL4GoD]

ok you dont even say what that is. it was cool looking, but I can't say that I'm impressed because i dont even know what's going on in that.. what.. less than 20 second clip? please explain that.

[LordKnex]

Amazing! I do alot of science at home, but I've never seen anything like that. How is it done?
