Across a jet wing which consequence results when the boundary Reynolds number exceeds design?

A)Transition to turbulent flow occurs
B)Increased laminar flow is sustained
C)Pressure gradient reverses steadily now
D)Lift coefficient estimates become linear

💡 Explanation

The transition to turbulence occurs because increased Reynolds number leads to instability via Tollmien-Schlichting waves, thus leading to turbulent flow rather than sustained laminar flow because laminar flow is only sustained at very low Reynolds numbers.
