Fuck Yeah Fluid Dynamics celebrates fluid dynamics in all their fuck-yeahness.

Some of these are pretty cool, but if I never see another fuckyeah[SOME RANDOM SHIT].tumblr.com url, I will be happier for it.

When everything is Fuck Yeah, then nothing is Fuck Yeah.

It would be nice if they credited the experimenters.

It's only appropriate that this is where "Fuck, Yeah!" Jumps the Shark, because without Fluid Dynamics, Jumping a Shark might not be possible!

If they wanted some real Fuck Yeah material, they'd go for the astrophysical simulation groups, crunching lots of very hard numbers in rooms with quite a few computers all chattering together. You think fluid dynamics is hard? Ha! Wait until you have to deal with the fluid being magnetic: magnetohydrodynamics. Or near significant distortions of spacetime: general relativistic hydrodynamics. Or moving very quickly, ultra (at which point you're left wondering, "Which relativistic did you mean, special (fast) or general (lots of mass)?" Ultra-relativistic magnetohydrodynamics, because your numerical simulation is just not hard enough with your candy-ass Navier–Stokes equations being applied to dull old non-magnetic matter that isn't moving about around c, relative to other parts of the same flow. You want to know what kinds of jets of plasma are going to get whipped off when you drop a star into a rotating black hole, here you go! That's a real tumble.

I am all for more fuck-yeah science. Fuck-yeah FORTRAN routines to simulate fluid dynamic may be harder to make sexy though.

Yes. Yes I did. Probably would have helped to go to class once in a while.

Your words have excited me in my pants.

Exhibit 1:

Exhibit 2:

"Excursion funnels are part of an investigation into how well test subjects can solve problems while traveling through a churning funnel of liquid asbestos. Results so far are very informative: They cannot."

- Aperture Science

Adipocere, I am totally on to you.

Yeah, I was breathing kind of heavily by the end of that comment.

Next person I talk too, I'm gonna sneak that into the conversation somehow, because yeah...or Fuck Yeah...that makes my pants happy.

Also, it's mind boggling that anything can snap 2000 or 3000 frames per second and catch a droplet of water be so whole for so long. i wonder what such a machine sounds like...

It would be a good name for a journal, tho.

Skygazer: These days they're electronic (e.g.) and presumably silent. There are 10,000-frames-per-second film cameras, though.

So how do airplanes fly upside down?
posted by warbaby at 6:15 AM on October 15, 2010

Same way they fly rightside-up.

By taking off from a conveyor belt.
posted by inigo2 at 1:49 PM on October 15, 2010 [1 favorite]

turn this airfoil upside down and the lift arrow points down. What's the opposite of lift? Fall? Well, then the airfoil is generating fall. And that's what the plane would do. Except they don't and planes can fly upside down, so how are they generating lift when the plane is upside down?
posted by warbaby at 2:23 PM on October 30, 2010

I can't tell if you're serious or trolling, warbaby. In case it's the former, the answer is by changing the angle of attack. This in fact is how most planes actual;ly get off the ground in the first place-- the pilot pulls the nose up, which changes the angle of attack to magnify the lift generated by the shape of the wing itself.
posted by dersins at 2:44 PM on October 30, 2010

warbaby: Aircraft can fly with symmetric airfoils, too. The reason is that the angle of attack varies, and so the stagnation point or separation point moves to a different point on the leading edge of the airfoil.

(If the diagram you linked to were in an aerodynamics text, this would probably be explained within a page or two of the diagram)
