WER-37 rev: Performance and aerodynamic braking of a horizontal-axis wind turbine from small-scale wind tunnel tests
(Wichita State University. Center for Energy Studies, 1985-07)Wind tunnel tests of three 20-inch diameter, zero-twist, zero-pitch wind turbine rotor models have been conducted in the WSU 7' x 10 1 wind tunnel to determine the performance of such rotors with NACA 23024 airfoil and ... -
WER-4: Wind characteristics for the western part of Kansas
(Wichita State University. Wind Energy Laboratory, 1978-02)The Kansas stations show power densities of from 175 to 200 W/m2 at a height of 25 ft. Using the 3/7 power law, a 200 W/m2 power density would increase to 360 W/m2 at a height of 100 ft and to 490 W/mZ at 200 ft. There ... -
WER-5: Wind power estimation in the Great Plains
(Wichita State University. Wind Energy Laboratory, 1978-11)Some aspects of wind power estimation are examined. Confidence intervals for wind power density are calculated from existing National Weather Service wind data for the Great Plains area. Correlation of yearly mean wind ... -
