Circulation around a wing

WebJul 23, 2024 · The circulation is a line integral around an arbitrarily-chosen closed curve within the space occupied by the fluid. Its value depends on the curve, velocity of the fluid on the curve, and the direction (e.g., clockwise or counterclockwise) in which the curve is traversed. The circulation is defined as Γ = ∮→u ⋅ d→ℓ. WebMay 20, 2008 · "Circulation" around a wing deceases as air speed increases. As air speeds approach mach 1, for example a 747 flying at mach .85 to mach .90, there is no significant forward (relative to a wing) flow of air anywhere on a wing. The axis of wing tip vortices is close to parallel to the direction of travel. The axis of turbulent vortices above …
