Wind-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 ...

Interaction of atmospheric boundary layer flow with wind turbines

Majid Bastankhah

As wind turbines operate within the atmospheric boundary layer (ABL), the study of their interaction with the ABL flow can help us better understand and predict their performance. In addition to the performance of wind turbines, this interaction has an eff ...

A New Miniature Wind Turbine for Wind Tunnel Experiments. Part I: Design and Performance

Fernando Porté Agel, Majid Bastankhah

Miniature wind turbines, employed in wind tunnel experiments to study the interaction of turbines with turbulent boundary layers, usually suffer from poor performance with respect to their large-scale counterparts in the field. Moreover, although wakes of ...

2017

Comprehensive wind tunnel experiments were carried out to study the interaction of a turbulent boundary layer with a wind turbine operating under different tip-speed ratios and yaw angles. Force and power measurements were performed to characterize the var ...

A New Miniature Wind Turbine for Wind Tunnel Experiments. Part II: Wake Structure and Flow Dynamics

Fernando Porté Agel, Majid Bastankhah

An optimized three-bladed horizontal-axis miniature wind turbine, called WiRE-01, with the rotor diameter of 15 cm is designed and fully characterized in Part I of this study. In the current part of the study, we investigate the interaction of the turbine ...

Experimental and theoretical study of wind turbine wakes in yawed conditions

Fernando Porté Agel, Majid Bastankhah

This work is dedicated to systematically studying and predicting the wake characteristics of a yawed wind turbine immersed in a turbulent boundary layer. To achieve this goal, wind tunnel experiments were performed to characterize the wake of a horizontal- ...

Analytical modeling of turbine wakes in yawed conditions

Fernando Porté Agel, Majid Bastankhah

Increasing wind energy production has become a unanimous plan for virtually all the developed countries. In addition to constructing new wind farms, this goal can be achieved by making wind farms more efficient. Control strategies in wind farms, such as ma ...

A wind-tunnel investigation of wind-turbine wakes in yawed conditions

Fernando Porté Agel, Majid Bastankhah

Wind-tunnel experiments were performed to study the performance of a model wind turbine and its wake characteristics in a boundary layer under different operating conditions, including different yaw angles and tip speed ratios. High-resolution particle ima ...

A wind-tunnel investigation of wind-turbine wakes in different yawed and loading conditions

Fernando Porté Agel, Majid Bastankhah

Wind-turbine wakes have negative effects on wind-farm performance. They are associated with: (a) the velocity deficit, which reduces the generated power of downwind turbines; and (b) the turbulence level, which increases the fatigue loads on downwind turbi ...
