WINTWEX-W WINd Turbine Wake EXperiment Wieringermeer (.0 05.0) Goal: single wind turbine wake characteristics Campaign setup: wind measurements up and downstream of a.5 MW Nordex wind turbine Instrumentation: Windcube v, Windcube 00S, Windcube v, Zephir, WindIris & SUMO Main results: TI is highest on wake flanks and averages to a conical area of increased TI over time. Wakes are strongest in stable conditions, leading to a lower power output. Slide / ESWJ 05
