Eli5 cross draft

511 views

Could anybody explain to me if I open two windows in my home, when there isn’t any wind outside, why a cross draft occurs and would there ever be an instance where a cross draft couldnt happen even if its windy?

Thanks so much!

As for the second part of the question, it may be possible that a U-shape or some peculiar house could be designed in such a way to minimize draft and keep even pressure to prevent wind

…but highly unlikely due to nature’s desire to move instead of stay still.

So I don’t know how it could be possible but I wouldn’t be in shock if a mathematician figured it out.
