Circulation around a wing
WebThe circulation around its core depends on its strength, denoted by Γ. Consider an infinitely small vector segment dl along the filament and some arbitrary point P in space. The small segment will induce a velocity dw at the point P, whose magnitude can be determined using the so-called Biot-Savart Law5: Sign in to download full-size image WebNov 27, 2024 · Because the wing is in motion, the circulation may not be fully closed, but the lower pressure areas created by the airfoil as it passes through the air imparts energy to the air in a similar manner as the pump …

The equation states that the lift L per unit length along the cylinder is directly proportional to the velocity V of the flow, the density r of the flow, and the strength of the vortex G that is established by the rotation. L = r * V * G
