Towards an improved understanding of wind turbine wakes in complex terrain
In this thesis, we explored the effect of certain terrain-induced flow phenomena on the development of wind turbines sited in complex terrain. A combined experimental and analytical approach is used to study wind turbine wakes in different types of complex ...
EPFL2024Power performance of a model floating wind turbine subjected to cyclic pitch motion: A wind tunnel study
Fernando Porté Agel, Guiyue Duan, Daniele Gattari
Wind tunnel experiments were performed with a miniature floating wind turbine model to study the effects of cyclic pitch motion on its power performance. The cyclic pitch motion was prescribed by two key parameters: pitch frequency and amplitude. The power ...
IOPscience2024Wind 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 ...
2024Dynamic stall characterisation and control for vertical-axis wind turbines
According to the International Energy Agency, the global net-zero emissions objective requires the installed wind power capacity to increase 11-fold between 2020 and 2050. The scientific community has recently voiced concerns about the logistic feasibility ...
EPFL2023Wind Turbine Wakes in Active Yaw Control: Numerical and Theoretical Studies
In this thesis, we explore the best practice of simulating the wakes of the turbines under active yaw control (AYC) using large-eddy simulation (LES). In the first study, we validate the blade-element actuator disk model (ADM-BE) for a yawed wind turbine. ...
EPFL2023A wind tunnel study on cyclic yaw control in a wind farm model
Fernando Porté Agel, Guiyue Duan
Dynamic control strategies, such as dynamic induction control [1], were reported as efficient and beneficial in improving wind farm power production. A recent work based on computational fluid dynamics simulation [2] shows that by controlling wake meanderi ...
2023Wind farm power density optimization according to the area size using a novel self-adaptive genetic algorithm
Fernando Porté Agel, Nicolas Otto Kirchner Bossi
This work studies the power density (PD) optimization in wind farms, and its sensitivity to the available area size. A novel genetic algorithm (PDGA) is introduced, which optimizes PD and the turbine layout, by self-adapting to the PD and to the solutions ...

Fernando Porté Agel, Arslan Salim Dar, Guiyue Duan
In this study, wind-tunnel experiments are used to investigate cyclic yaw control as a wake mitigation strategy aiming to improve wind farm power production. The control strategy is applied to a single wind turbine and a wind farm comprising of a column of ...
2023An experimental and analytical study of wind turbine wakes under pressure gradient
Fernando Porté Agel, Arslan Salim Dar, Abraham Starbuck Gertler
This work is dedicated to the systematic investigation of wind turbine wakes under the effect of pressure gradients. Wind tunnel experiments are carried out with a wind turbine positioned on straight ramps of increasing angle such that it experiences an ap ...
