Assessment of the aerodynamic benefits of collocating horizontal- and vertical-axis wind turbines in tandem using actuator line model

The actuator line model is used to study the vertically staggered wind turbine cluster composed of horizontal- and vertical-axis turbines (HAWTs VAWTs) in a tandem layout. We consider three simple configurations, including VAWT upwind HAWT (V + H), downwind (H V), between two HAWTs V H). A installed can not only generate power by itself but also enhance generation HAWT, total increases about 100 kW. When downstream presence slightly reduces efficiency HAWT. However, utilizes increased speed ground generates more power. 60 HAWTs, beneficial effects on are manifested. Nevertheless, still 50 kW than that without VAWT. Overall, even layout where wake most pronounced, collocation VAWTs utilize otherwise wasted resources, thus increasing density farms.
