Data from: Optimal blade pitch control for enhanced vertical-axis wind turbine performance
Karen Ann J Mulleners, Sébastien Le Fouest
This directory contains open-source data obtained using a single-bladed H-type vertical-axis wind turbine prototype with individual blade pitching. This data results from the optimisation of the blade's pitching kinematics using a genetic algorithm at two ...
Zenodo2024Wind turbine wake superposition under pressure gradient
Fernando Porté Agel, Arslan Salim Dar
We investigate the effect of pressure gradient on the cumulative wake of multiple turbines in wind tunnel experiments spanning across a range of adverse pressure gradient (APG), zero pressure gradient (ZPG), and favorable pressure gradient (FPG). Compared ...
2024Identifying aerodynamics of small fixed-wing drones using inertial measurements for model-based navigation
Jan Skaloud, Gabriel François Laupré
The success of drone missions is incumbent on an accurate determination of the drone pose and velocity, which are collectively estimated by fusing iner- tial measurement unit and global navigation satellite system (GNSS) mea- surements. However, during a G ...

2023Numerical study on the scale effect of tip vortex cavitation induced by incoming velocities and scale ratios
Mohamed Farhat, Huaiyu Cheng, Mohan Xu
Large eddy simulations of tip vortex cavitation (TVC) around an elliptical hydrofoil is performed to study its scale effect. A satisfying agreement is obtained between the numerical and experimental data. It indicates that the scale effect of TVC is remark ...
PERGAMON-ELSEVIER SCIENCE LTD2023The dynamic stall dilemma for vertical-axis wind turbines
Karen Ann J Mulleners, Sébastien Le Fouest
Vertical-axis wind turbines (VAWT) are excellent candidates to complement traditional wind turbines and increase the total wind energy capacity. Development of VAWT has been hampered by their low efficiency and structural unreliability, which are related t ...
PERGAMON-ELSEVIER SCIENCE LTD2022Effects of leading-edge separation on the vortex-induced vibration of an elongated bluff body
Wind-tunnel experiments were conducted to investigate the effects of leading-edge separation on the vortex-induced vibration (VIV) of an elastically-supported elongated bluff body. Solid wind barriers of various heights were fixed in the leading edge to ad ...
ELSEVIER2021An experimental study on the upper part-load elliptical vortex instability in a Francis turbine
François Avellan, Elena Vagnoni, Arthur Tristan Favrel, Andres Müller, Ali Amini
This paper presents preliminary results of an experimental study on the occurrence and development of the upper part-load instability in a reduced-scale Francis turbine. The study includes draft tube pressure measurements, high-speed flow visualization, an ...
