Report

Aerodynamic Performance and Impact Analysis of a MEMS-Based Non-Invasive Monitoring System for Wind Turbine Blades

Autor: Schärer, Nicolas, Mikhaylov, Denis, Sievi, Cédric, Hanna, Badoui, Braud, Caroline, Deparday, Julien, Barber, Sarah, Polonelli, Tommaso, Magno, Michele

Wind power generation plays a crucial role in transitioning away from fossil fuel-dependent energy sources, contributing significantly to the mitigation of climate change. Monitoring and evaluating the aerodynamics of large wind turbine rotors is cru

Report

Study of the wall pressure variations on the stall inception of a thick cambered profile at high Reynolds number

Autor: Braud, Caroline, Podvin, Bérengère, Deparday, Julien

Publikováno v: Phys. Rev. Fluids 9 (2024) 014605

We present an experimental study of the aerodynamic forces on a thick and cambered airfoil at a high Reynolds number 3.6 x 10^6, which is of direct relevance for wind turbine design. Unlike thin airfoils at low chord-based Reynolds numbers, no consis

Report

Experimental quantification of unsteady leading-edge flow separation

Autor: Deparday, Julien, He, Xiaowei, Eldredge, Jeff D., Mulleners, Karen, Williams, David R.

Publikováno v: Journal of Fluid Mechanics 941 (2022) A60

We propose here a method to experimentally quantify unsteady leading-edge flow separation on aerofoils with finite thickness. The methodology relies on the computation of a leading-edge suction parameter based on measured values of the partial circul

Report

The dynamics and timescales of static stall

Autor: Fouest, Sébastien Le, Deparday, Julien, Mulleners, Karen

Airfoil stall plays a central role in the design of safe and efficient lifting surfaces. We typically distinguish between static and dynamic stall based on the unsteady rate of change of an airfoil's angle of attack. Despite the somewhat misleading d

Etudes expérimentales de l'Interaction fluide-structure sur les voiles de bateaux au portant

Autor: Deparday, Julien

Cette thèse présente une étude expérimentale sur un voilier instrumenté, menée pour décrire le comportement aéro-élastique des voiles et du gréement pour des navigations au portant. Les formes des voiles utilisées sont des surfaces non dé
