Behavior of bats at wind turbines [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Bats are dying in unprecedented numbers at wind turbines, but causes of their susceptibility are unknown. Fatalities peak during low-wind conditions in late summer and autumn and primarily involve species that evolved to roost in trees.

Wind turbine reliability data review and impacts on levelised cost of energy
Wind Energy, 2019 Reliability is critical to the design, operation, maintenance, and performance assessment and improvement of wind turbines (WTs). This paper systematically reviews publicly available reliability data for both onshore and offshore WTs and investigates the

, 2018 It uses a radically new approach to capturing wind energy. The device captures the energy of vortices,an aerodynamic effect that has plagued structural engineers and architects for ages (vortex shedding effect). As the wind bypasses a fixed structure,its flow changes and generates a cyclical pattern of vortices. Once these forces are strong enough,the

On the scaling of wind turbine rotors [PDF]
Wind Energy Science, 2020 Abstract. This paper formulates laws for scaling wind turbine rotors. Although the analysis is general, the article primarily focuses on the subscaling problem, i.e., on the design of a smaller-sized model that mimics a full-scale machine. The present study considers both the steady-state and transient response cases, including the effects of ...
