The Kutta-Joukowski theorem is a fundamental principle in aerodynamics that relates the lift force generated by an airfoil to the circulation around the airfoil in potential flow theory. It provides a mathematical relationship between the lift, fluid velocity, and the geometry of the airfoil in a simplified, inviscid flow scenario.
- L = Lift force acting on the airfoil
- ρ = Fluid density (density of the air in most cases)
- V∞ = Free-stream velocity of the fluid approaching the airfoil
- Γ = Circulation around the airfoil
