← ScienceWhich consequence results when rapid fluid flow generates turbulence around an airplane wing, assessed using the Navier-Stokes equation?
A)Increased skin friction coefficient immediately occurs
B)Overall pressure increases on airfoil surface
C)Lift decreases due to boundary separation✓
D)Elevated temperature via the Peltier effect
💡 Explanation
The turbulent flow causes boundary layer separation on the airfoil, where viscous forces overcome the pressure gradient, therefore lift decreases dramatically, rather than pressure increasing because the separated flow reduces the effective size.
