✈️ Joukowski Airfoil: Kutta Circulation, Pressure Field and Lift (2D)

Side view of inviscid potential flow around a Joukowski airfoil. Set angle of attack, speed, air density, thickness and camber, and read the circulation fixed by the Kutta condition, the pressure coefficient around the surface, the lift per metre of span and the streamlines. The lift is checked two independent ways, by integrating the pressure and by the Kutta-Joukowski law, with four in-page numerical checks.
