Vortex Shedding - Smarter Every Day 23
A brief look at what phenomenon causes a vortex behind airplanes. Oh, and an A-10 Warthog.

[Engines screaming] Hey it's me, Destin. We're at an airshow. So today I'm going to teach you about vortex shedding. [Music] [Engines screaming] (Man) YEAH! (Destin) Fly... flying our airplanes. [Engine roaring] (Destin) I can't hear you. Why does the smoke come out of the airplane? (Sadie) To help it go better. - Makes perfect sense. [Engine roaring] [Propellers thumping] So on a wing... You know, in layman's terms, the Bernoulli principle - where flow is high, pressure's low. Got it? Where flow is high, pressure's low. So the air has to travel farther over the top of the wing than on the bottom, so it's flowing faster. So we have low pressure on top and high pressure on the bottom. So high pressure pushes the airplane up. That's why the airplane flies. But something you didn't know: if you're on the ...
