← ScienceWhich 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.
