So circulation forms and self-sustains naturally when you push the airfoil through the air. From the article, it looks like this is because the air behavior is asymmetric between the leading and trailing edges, in favor of maintaining circulation.
My question: why/how does the air do this?
For example, I thought the Coanda effect was the macro result of van der Waals attraction. Is there a similar explanation for the behavior of air which results in asymmetric leading & trailing edge behavior?
- camperman 16y agoBecause it's a fluid that has pressure and velocity everywhere, like all fluids. I don't know how you would describe circulation in terms of a macro result of some other effect.
