WebWhen there is no friction between flow lines, the only way flow velocity can change is via this pressure driven acceleration and deceleration. The air entering low pressure area on top of the wing speeds up. The air entering high pressure area on bottom slows down. That is why air on top moves faster. 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.
