What is Rayleigh's contribution to aerodynamic lift?
Circulation theory
Bernoulli's principle
Coanda effect
Magnus effect
Answer
Circulation theory, developed by Lord Rayleigh, explains aerodynamic lift by attributing it to the circulation of air around an airfoil. According to this theory, the curved shape of the airfoil causes the air flowing over the top surface to travel faster than the air flowing over the bottom surface, creating a pressure difference that generates lift. This circulation is maintained by the airfoil's shape and the viscosity of the air.
