I thought Bernoulli described how faster moving air...
...caused an effective decrease in air pressure. Not an increase in airspeed (which is kinda circular).
Likewise, I've never heard Bernoulli applied to concave surfaces before. I would guess the affect would be a lot more complicated. What drives Bernoulli on a convex surface is the fact that air molecules cannot inhabit the same space as wing molecules - they *must* take the longer path. For concave surfaces no such physical limitation exists.
Admitting in advance that my not hearing of something is not very compelling.
