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
Offshore floating wind turbines (OFWTs) are becoming increasingly popular due to their ability to exploit deep-sea wind resources. However, since wind turbines are installed on floaters instead of solid foundations, the dynamic response of an OFWT due to ...
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. ...
EPFL2023Characterization of wind turbine flow through nacelle-mounted lidars: a review
Fernando Porté Agel, Peter Andreas Brugger
This article provides a comprehensive review of the most recent advances in the planning, execution, and analysis of inflow and wake measurements from nacelle-mounted wind Doppler lidars. Lidars installed on top of wind turbines provide a holistic view of ...
2023Large-Eddy Simulation of Wind Turbine Flows: A New Evaluation of Actuator Disk Models - Dataset
Fernando Porté Agel, Tristan Revaz
Main data used in the following paper: Revaz, T.; Porté-Agel, F. Large-Eddy Simulation of Wind Turbine Flows: A New Evaluation of Actuator Disk Models. Energies 2021, 14, 3745. https://doi.org/10.3390/en14133745 ...
EPFL Infoscience2022Mean kinetic energy distribution in finite-size wind farms: A function of turbines' arrangement
Varun Sharma, Marc Calaf Bracons, Roberto Torres Sánchez
In this work the redistribution and recovery of mean kinetic energy in a realistic, finite size wind farm is studied for neutral atmospheric boundary layer conditions. Five different wind farm configurations, with different wind turbine arrangements, are c ...
PERGAMON-ELSEVIER SCIENCE LTD2020Wind-Turbine and Wind-Farm Flows: A Review
Fernando Porté Agel, Majid Bastankhah, Sina Shamsoddin
Wind energy, together with other renewable energy sources, are expected to grow substantially in the coming decades and play a key role in mitigating climate change and achieving energy sustainability. One of the main challenges in optimizing the design, o ...
2019Characterization of Wind Turbine Wakes with Nacelle-Mounted Doppler LiDARs and Model Validation in the Presence of Wind Veer
Fernando Porté Agel, Peter Andreas Brugger, Corey Dean Markfort, Fernando Carbajo Fuertes, Mohsen Vahidzadeh
Accurate prediction of wind turbine wakes is important for more efficient design and operation of wind parks. Volumetric wake measurements of nacelle-mounted Doppler lidars are used to characterize the wake of a full-scale wind turbine and to validate an a ...
2019Multi-Objective Wind Farm Layout Optimization with unconstrained Area Shape
Fernando Porté Agel, Nicolas Otto Kirchner Bossi
It is well known that turbine wakes are responsible for considerable power losses in a wind farm. In the last two decades Wind Farm Layout Optimization (WFLO) has been extendedly used to model the minimization of such wake effects in the attempt to maximiz ...
