Wind Turbine Blade Aerodynamics

A typical drag coefficient for wind turbine blades is 0.04; compare this to a well-designed automobile with a drag coefficient of 0.30. Even though the drag coefficient for a blade is fairly constant, as the wind speed

The governing equation for power extraction is: where P is the power, F is the force vector, and u is the velocity of the moving wind turbine part. The force F is generated by the wind''s interaction with the blade. The magnitude and distribution of this force is the primary focus of wind-turbine aerodynamics. The most familiar type of aerodynamic force is drag. The direction of the drag force is parallel to the relative wind. Typically, the wind turbine parts ar

Wind-turbine aerodynamics

To extract power, the turbine part must move in the direction of the net force. In the drag force case, the relative wind speed decreases subsequently, and so does the drag force. The relative wind aspect dramatically limits

Enhancement of Lift and Drag Coefficients of Wind Turbine Using

In this study, the lift (CL) and drag (CD) coefficients are treated as quality responses, and hence the higher is better (HB) is used for maximizing the lift coefficient and the lower is better (LB) used for minimizing the drag
