This project is experimental and investigates the performance of twelve model wind turbines in a wind tunnel. When wind turbines are placed in a wind farm, the power production falls dramatically, because the wind turbines create wakes and thereby ‘shadow’ each other. This projects aims to improve the efficiency of wind farms, by giving the wind turbines alternating mast heights. In this way the wake-to-wake interaction is decreased which leads to a better performance of the wind farm as a whole.
