Selected wind tunnel test results for the Darrieus wind turbine
Five blade configurations of a 2-m-diam Darrieus wind turbine have been tested in the Vought Corporation 4.6- x 6.1-m (15- x 20-ft) Low-Speed Wind Tunnel. Rotor solidity, Reynolds number, and freestream velocities tested were in the following ranges: solidity, 13 to 30%; Reynolds number, 1 to 3 x 10/sup 5/; freestream velocity, 7 to 11 m/s. The airfoil selection for all configurations was NACA 0012. The parameters measured were rotor torque, rotor rotational speed, and tunnel conditions. Data are presented in the form of power coefficient as a function of tip-speed ratio along with comparative results from an analytical model.
