In a continuing effort to study and characterize various types and sizes of wind turbine generator wakes a test program was conducted at the FloWind 170 kW vertical axis wind turbine (VAWT) near Ellensburg, Washington. Oregon State University (OSU) scientists measured the wake behind the 90 ft. tall Darrieus VAWT using fixed place and portable kite anemometers. Downwind velocity deficits were measured from 3-9 diameters along the wake centerline at rotor midpoint (55 ft.) and perpendicular to the wake. Wake turbulence characteristics were also measured. The measured velocity deficits were compared to wake model calculations.
