Which outcome occurs when wind turbine blade Reynolds number increases?

A)Increased trailing edge stall margin
B)Increased risk of laminar separation
C)Decreased parasitic power losses
D)Decreased rotor-induced vibration noise

💡 Explanation

Increased Reynolds number promotes unstable laminar flow, triggering laminar separation because the flow is more sensitive to adverse pressure gradients; therefore stall risk increases, rather than losses decreasing under these potentially turbulent transitional conditions.
