------ Isn't it also true that geometric anhedral partially inhibits spanwise flow, increasing effeciency to a point?
I am guessing that you consider anhedral to have an effect of "trapping" high pressure air beneath the wing -- air that would otherwise partially leak away spanwise, particularly as compared to a wing with dihedral. That effect would theoretically be there, but I doubt if you could even measure it with any confidence, except in very close ground-effect.
Yeah, I read something like that somewhere. It reduces vortex strength, leaving more energy available for lift.
