Unformatted text preview: The actual relationship between ( λ ) and c p is dependent on the turbine design. A threebladed (DU93W210 airfoil) wind turbine with a rotor diameter of 50m using near optimum tapered and twisted blades rotates at a speed of 25 rpm. For wind speeds from 5m/s to 10m/s, calculate the power for the system. Plot c p as a function of the tip speed ratio. Also plot the power as function of wind speed. Comment on each graph. Assume an angle of attack of 4 degrees for the airfoil. P = 1 2 c p Au 3 λ = T R u...
