Wind 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 ...
2024Towards 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 ...
EPFL2024The effect of nacelle-to-rotor size on the wake of a miniature wind turbine
Fernando Porté Agel, Arslan Salim Dar, Rim Majzoub
Wind tunnel experiments are performed to investigate the effect of nacelle-to-rotor size on the wake of a wind turbine under different Reynolds numbers. Four different turbine configurations are tested, which vary in the rotor diameter and nacelle length a ...

2024An 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 ...
2023A wind tunnel study on cyclic yaw control: Power performance and wake characteristics
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 investigation of a roof-mounted horizontal-axis wind turbine in an idealized urban environment
Fernando Porté Agel, Arslan Salim Dar, Guillem Armengol Barcos
Wind-tunnel experiments are performed to investigate the effect of minor modifications to the roof edge shape on the power performance and wake characteristics of a horizontal-axis wind turbine sited on a cube-shaped building. Three roof edge shapes are co ...
2022Wind turbine wakes on escarpments: A wind-tunnel study
Fernando Porté Agel, Arslan Salim Dar
In this study, the wake behind a wind turbine located on an escarpment is investigated using particle-image velocimetry in a wind tunnel. Five different escarpment models are used, which vary in the windward side shape from forward facing steps (FFS) with ...

EPFL Infoscience2022Three-dimensional wind-turbine wake characterization via tomographic particle-image velocimetry
Fernando Porté Agel, Arslan Salim Dar
Wind turbines are often sited on different topographical features. In the current work, we performed wind-tunnel measurements of the wake behind a single wind turbine sited on two escarpments differing in the windward side shape using tomographic particle- ...
