← ScienceWhich flow state results when the Reynolds number exceeds predicted bounds in aircraft design?
A)Early onset, laminar boundary separation
B)Fully separated turbulent boundary layer✓
C)Delayed transition due viscous suppression
D)Increased lift induced drag reduction
💡 Explanation
A high Reynolds number indicates a dominance of inertial forces over viscous forces, triggering turbulence; specifically, boundary layer transition. Therefore, turbulent separation occurs, rather than laminar separation, because higher momentum fluids energize boundary near the surface reducing thickening.
