Have you ever thought about how airplane wings work ? As they produce an incredible amount of lift ? Technology aerodynamic taught people to fly. An airplane wing works because of the interesting fluid mechanics for profiles. Wind turbines, gas turbines and hydraulic machines, all work on the principles of the wing. This video tells physics for a simple form that has revolutionized the engineering world.
Work profile is explained with the help of the Coanda effect and the principle curvature flow. The drawback of arguments based on a Bernoulli is shown both experimentally and theoretically.
