← ScienceWhen jet fuel flows past an aircraft wing at a high Reynolds number, which behavior results from boundary layer transition?
A)Increased skin friction drag✓
B)Decreased pressure gradient effects
C)Improved lift coefficient stability
D)Reduced vortex shedding frequency
💡 Explanation
Increased friction drag occurs because transition to turbulence increases momentum transfer within the boundary layer, therefore increasing shear stress at the surface rather than maintaining a laminar flow, that reduces friction under ideal conditions.
