  • $\begingroup$ The figure seems to be showing a flow with approximately zero lift, which I don't think your answer would explain. $\endgroup$ Commented Apr 17, 2019 at 16:41
  • $\begingroup$ @D.Halsey I revised the diagram. Why don't you think it's impossible to explain? $\endgroup$ Commented Apr 17, 2019 at 21:56

    $\begingroup$ I think there is some good physics here but I don't think you are correct when you say Bernoulli's theorem does not apply. It applies along flowlines for laminar flow. $\endgroup$ Commented Sep 22, 2020 at 11:25

    $\begingroup$ It may be a case of terminology. Some people interpret the phrase "Bernoulli theorem" to mean the result of the Bernoulli equation for incompressible fluid; others take it to mean the more general result for a compressible fluid. $\endgroup$ Commented Sep 22, 2020 at 11:29
  • $\begingroup$ @AndrewSteane Because wings have an angle of attack, the direction of air velocity is at an angle to the upper surface, which causes the flowing air to have a tendency to move away from the wing along the normal to the upper surface of the wing, resulting in low pressure. $\endgroup$ Commented Oct 9, 2024 at 22:56
