← ScienceWhich flow regime reduces predicted lift when applying Bernoulli's equation above a stalled airfoil?
A)Increased adverse pressure gradient effect
B)Boundary layer separation occurrence✓
C)Turbulent kinetic energy dissipation
D)Reduced skin friction coefficient gains
💡 Explanation
Boundary layer separation reduces predicted lift because it fundamentally changes airflow; the flow no longer smoothly follows the airfoil's surface. Flow separation introduces significantly complex circulation patterns rather than behaving according to Bernoulli's equation, therefore predicted lift is lower than observed.
