Hello everyone,
I am pondering on the airflow around a wing:
When air flows over a wing, part of the air goes below the wing and part over the wing. Even when the air is moving, the pressure at a point in space is always isotropic. The pressure on top of the wing is slightly lower than than the free stream pressure. This pressure distribution produces a net force ##L _{top} ## on top of the wing directed downward. The pressure at the bottom of the wing is slightly larger than the free stream pressure farther away from the wing and produces a net lift force ##L _{bottom}##. The difference between these two forces, one pointing down and one pointing up, produces the overall lift force ##L_{total}= L _{top} - L_{bottom}## directed upward.
Does the static air located far above the wing rush toward the top of wing since it is at a higher pressure than the air closer to the wing? Also, the higher pressure air below the wing should push both on the bottom surface of the wing and also on the air farther below the wing. Is that what happens?
Thanks!
