Which flow regime results when Reynolds number increases significantly in aerofoils?

A)Laminar separation bubble formation increases drag
B)Increased boundary layer thickness decreases lift
C)Transition to turbulence begins closer leading
D)Pressure gradients cause total flow stagnation

💡 Explanation

Transition to turbulence occurs closer to the leading edge because an increased Reynolds number amplifies instabilities through inertial forces overcoming viscous damping. Therefore, turbulence arises faster, rather than a stable layer, because the ratio promotes disruption before complete stabilization.
