Hmm.. how "grand scale" are we talking?
From a logical view, I'd say it's not something to be concerned about. If this was the case, wouldn't a large city produce nearly the same effect with so many tall buildings?
Pretty simple question:
Is it possible to completely calculate Lift and Drag from the pressure distribution over an airfoil?
Atm, I have Lift worked out as well as the Induced drag ( correct me if I'm wrong. ) but am having trouble working out how it would be possible to get the skin...
