Detection of wind turbines rotary motion by birds: A matter of speed and contrast
Some bird species may detect low‐speed rotation on wind turbines as static. A low contrast between the wind turbine and its background increases the rotation speed treshold at which this phenomenon appears. Automatic Detection Systems used to slow down wind turbines when birds are approaching may thus be counterproductive.

We demonstrate on a short‐lived, endangered raptor species, the Lesser kestrel, that additional mortality due to windfarms can have a negative impact on population growth rate. Although the impact is currently moderate, the forecasted decrease in immigration rate, and increase in the number of windfarms at a wider scale, may threaten the recovery of ...

Wind Turbines, Public Acceptance, and Electoral Outcomes
Abstract Despite a widespread public support for wind energy in general, wind turbine proposals attract a considerable amount of public opposition. At a time of political commitments to building more wind turbines for climate risk mitigation, we study the potential causes of this opposition and its electoral effects.

This study provides empirical evidence that wind turbines close to optimal habitats such as hedgerows strongly repel bats, while wind turbines located farther away in open areas could attract them. Increased risks of collisions and habitat losses near edges strengthen the importance of keeping wind turbines at a sufficient distance from woody edges (e ...

Assessment of Turbulence Models for Flow Simulation around a Wind Turbine Airfoil
This investigation focuses on the application of the computational fluid dynamics tool FLUENT to the study of flows over the NACA 63–415 airfoil at various angles of attack. With the aim of selecting the most suitable turbulence model to simulate flow around ice‐accreted airfoils, this work concentrates on assessing the prediction capabilities of ...

Etude numérique et expérimentale de l'écoulement autour d'un rotor éolien [PDF]
An improved model of an actuator surface is proposed, representing the flow around a wind turbine. This model was developed in conjunction with a Navier-Stokes solver using a blade element method for the calculation of power and wake development.
