Assessment of Turbulence Models for Flow Simulation around a Wind Turbine Airfoil

Modelling and Simulation in Engineering, Volume 2011, Issue 1, 2011., 2011
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 ...

Towards a better understanding of avian collision in wind energy facilities using automatic detection systems

Journal of Applied Ecology, Volume 62, Issue 6, Page 1437-1448, June 2025.
Data from automatic detection systems are a promising non‐invasive approach that requires few human and logistical resources to develop a more comprehensive bird collision risk mitigation strategy. They can be valuable to biodiversity stakeholders to highlight environmental factors that locally increase bird exposure and sensitivity, to avoid ...

Mineral dust emissions from proglacial valleys of western Canada: Historical and future dynamics

Earth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
Mineral dust emissions from proglacial valleys of western Canada remain unaccounted for in regional‐global estimates. We record 6‐years of dust emission activity and constrain meltwater and snow cover dynamics from 1984 to 2023, constraining key erodibility controls for aeolian processes.

L’opposition aux projets éoliens terrestres, une forme de contestation « territorialisée »

Géographie et Cultures, 2020
The aim of the article is to understand how opposition to wind energy is expressed locally, both in terms of substance and form, in order. The study illumi­nates the "paradox" of the energy transition: on the one hand, a relatively good acceptability of ...

Eoldist, a Web Application for Estimating Cautionary Detection Distance of Birds by Automatic Detection Systems to Reduce Collisions With Wind Turbines

Wind Energy, Volume 28, Issue 2, February 2025.
ABSTRACT The installation of automatic detection systems (ADSs) on operating wind energy facilities is a mitigation measure to reduce bird collisions. The effectiveness of an ADS depends on a combination of parameters, including the detection distance of the bird, its flight speed, and the time to complete the chosen action (e.g., turbine shutdown). We

Insectivorous bats alter their flight and feeding behaviour at ground‐mounted solar farms

Journal of Applied Ecology, Volume 61, Issue 2, Page 328-339, February 2024.
The negative effects of solar farms on bat flight and feeding behaviour should be considered when solar energy projects are planned. Research is needed to understand the mechanisms underlying the effects; for example, shading underneath solar panels may reduce plant biomass and therefore insect prey availability.

Optimisation d’un système de pompage éolien Application aux sites sahariens

Revue des Énergies Renouvelables, 2008
L’estimation des ressources en énergie éolienne présente une difficulté majeure. Contrairement aux réserves en combustible fossile, la quantité d’énergie disponible varie avec la saison et l’heure du jour.
