Why is the lamp smoking?

Peer pressure mostly.

Part of me thinks you posted this simply in the hopes that someone would ask that question, and you could make that joke.

is it your elbow? my elbows are always doing that.

What exactly is a live photo? I've heard people talk about it recently but I don't actually know what it is.

[–]FirestarPwns 11ポイント12ポイント  (4子コメント)

It's a new feature on the iPhone 6S. Basically when you take a picture, it records a few seconds before and after, so if you press harder on the screen, it shows a ~5 second video that may or may not give context to the picture. It's been done before, mainly by BlackBerry and HTC.

[–]Fanc1dan 23ポイント24ポイント  (3子コメント)

[–]HeAbides 17ポイント18ポイント  (17子コメント)

The buoyancy driven flow is laminar to start with, then transitions into an intermittent region of a toriodal quasi-steady nature before breaking up into turbulence at the top of the screen. This is phenomenal.

[–]nujiolk 4ポイント5ポイント  (5子コメント)

then transitions into an intermittent region of a toriodal quasi-steady nature

these are KH instabilities you noob

I also do not see any toroidal vortices

[–]HeAbides -2ポイント-1ポイント  (4子コメント)

The theory predicts the onset of instability and transition to turbulent flow in fluids

What? Umm yeah, they are KH instabilities, but that doesn't mean it isn't a transitional flow. I am surprised that you took the time to make a throwaway while not taking the time to read the darn wiki. The curl at the right hand edge definitely is a toroidal vorticy, though it is not purely axisymmetric.

[–]nujiolk 3ポイント4ポイント  (3子コメント)

I'm not arguing that it is not a transitional flow. KH facilitates downscale transfer. You're clearly just trying to sound smart when you don't understand shear instabilities.

"intermittent region of a toriodal quasi-steady nature" is nonsense when this is clearly KH. I still see no toroidal vortices. I just needed to call you on your bullshit

[–]HeAbides -3ポイント-2ポイント  (2子コメント)

Trollolol? I definitely understand shear instabilities. It is KH leading to an transitional region, it is quasi-steady and it has toroidal nature. Quit being so pedantic over semantics.

[–]nujiolk 4ポイント5ポイント  (1子コメント)

it has toroidal nature

You're talking nonsense

Quit being so pedantic over semantics

I hope to review your next paper

[–]HeAbides 0ポイント1ポイント  (0子コメント)

By saying toroidal nature all I meant was that the right half of the acknowledged asymmetrical flow emulates on the shape of a toroid. I'm sorry that got your panties in enough of a bunch as to merit a new account.

You're welcome to, as I put a lot more thought into the wording of my manuscripts than something on fucking /r/oddlysatisfying. Thanks for the impromptu peer review though.

[–]NaosuDunn 4ポイント5ポイント  (3子コメント)

Even more, you can clearly see why turbulence is a fractal phenomena.

[–]HeAbides 8ポイント9ポイント  (2子コメント)

Not sure why you are getting down votes :/

Big whirls have little whirls, that feed on their velocity,

And little whirls have lesser whirls, and so on to viscosity.

[–]NaosuDunn 2ポイント3ポイント  (0子コメント)

Haha probably there aren't a lot of fluid dynamics fans around here.

[–]HigginsBane 0ポイント1ポイント  (3子コメント)

I don't understand how turbulent flow can have a repeating pattern. Care to explain for me?

[–]HeAbides 0ポイント1ポイント  (2子コメント)

Between smooth laminar flow and turbulence there is a transitional region. The periodicity is within this transition, and is instigated by small oscillations, seen horizontal from the top of the lamp.

Full turbulence would be the more chaotic pattern seen at the very top of the frame.

[–]HigginsBane 0ポイント1ポイント  (1子コメント)

Right sorry, I should have been more specific. How does this gif make a perfect loop if there is turbulence?

[–]HeAbides 0ポイント1ポイント  (0子コメント)

Well the periodic transition is regular, but from the top section it looks like the OP faded a few of the first and last frames together. There are locations where the concentration of smoke simply disappear, not through diffusion or advection.

Can anyone who might know better confirm that this is Kelvin–Helmholtz instability?

[–]Theodorsfriend 1ポイント2ポイント  (0子コメント)

I don't know better but I think you're right. The air close to the lamp is warmer and goes up creating an area of lower pressure that moves the smoke to the left. Plus the smoke have initially laminar flow but one one side encounter the warm ascending air, gets momentum and goes up faster then the smoke one the other side crating the swirls.

[–]CaptainObvious_1 0ポイント1ポイント  (0子コメント)

Yeah it is. From the shear layer between the still cold air and warm smokey air.

Weed so dank the smoke rollin' itself a joint.

[–]Ferracoasta 1ポイント2ポイント  (3子コメント)

Why does this smoke swirl?

[–]CaptainObvious_1 1ポイント2ポイント  (2子コメント)

Kelvin helmholtz instability created from the shear layer (two flows at different velocities).

[–]DonBunny 0ポイント1ポイント  (1子コメント)

You are correct in attempting to apply a principle of fluid dynamics to answer this question, but I think a better explanation would be the turbulent flow is disrupting the laminar flow as the smoke moves into cooler air, causing the newer, warmer smoke to overtake the older, cooler smoke, thus creating the curl.

[–]CaptainObvious_1 1ポイント2ポイント  (0子コメント)

There isn't any turbulent flow before the formation of the vortical structures. The flow doesn't become turbulent until the breakdown of the structures, so I'm not sure where you're trying to go with your explanation.

Edit: to be a little more clear with what I'm saying: the cold air is for all purposes still and not moving, and the smoke is laminar for the beginning. Instabilities in the form of kelvin helmholtz instabilities begin forming and create the vortical structures, these structures grow and become unstable and breakdown into turbulent flow.

[–]nophoney 0ポイント1ポイント  (1子コメント)

I can understand why you would think that. It looks like the lamp is smoking and about to burst into flames. But what I think is happening, is they are just burning a stick of incense or a cigarette.

[–]Aiskhulos 2ポイント3ポイント  (0子コメント)

It's definitely incense. You can see the stick at the bottom. Also, it's pretty common for the smoke from incense to swirl like that.
