Wind-Turbine and Wind-Farm Flows: A Review

Fernando Porté Agel, Sina Shamsoddin, Majid Bastankhah

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 ...

Effect of aspect ratio on vertical-axis wind turbine wakes

Fernando Porté Agel, Sina Shamsoddin

Variability of the rotor aspect ratio is one of the inherent characteristics of vertical-axis wind turbines (VAWTs) which differentiates them especially from the more conventional horizontal-axis wind turbines. In this study, we intend to investigate the e ...

A model for the effect of pressure gradient on turbulent axisymmetric wakes

Fernando Porté Agel, Sina Shamsoddin

Turbulent axisymmetric wakes under pressure gradient have received little attention in the literature, in spite of their fundamental and practical importance, for example, in the case of wind turbine wakes over topography. In this paper, we develop an anal ...

Wind turbine wakes over hills

Fernando Porté Agel, Sina Shamsoddin

Understanding and predicting the behaviour of wind turbine wake flows over hills is important for optimal design of wind-farm configurations on topography. In this study, we present an analytical modelling framework together with large-eddy simulation (LES ...

Wind turbine wakes: exploring the underexplored : vertical-axis wind turbines and topography

Sina Shamsoddin

In this thesis, we aim to contribute to the research on two topics, namely, vertical-axis wind turbines (VAWTs) and wind turbines on topography. In the VAWT part, first, we implement two actuator-type VAWT parameterization models (i.e. the actuator swept- ...

Large-Eddy Simulation of Atmospheric Boundary-Layer Flow Through a Wind Farm Sited on Topography

Fernando Porté Agel, Sina Shamsoddin

Large-eddy simulation (LES) has recently been well validated and applied in the context of wind turbines over flat terrain; however, to date its accuracy has not been tested systematically in the case of turbine-wake flows over topography. Here, we investi ...

Turbulent planar wakes under pressure gradient conditions

Fernando Porté Agel, Sina Shamsoddin

Accurate prediction of the spatial evolution of turbulent wake flows under pressure gradient conditions is required in some engineering applications such as the design of high-lift devices and wind farms over topography. In this paper, we aim to develop an ...

A Large-Eddy Simulation Study of Vertical Axis Wind Turbine Wakes in the Atmospheric Boundary Layer

Fernando Porté Agel, Sina Shamsoddin

In a future sustainable energy vision, in which diversified conversion of renewable energies is essential, vertical axis wind turbines (VAWTs) exhibit some potential as a reliable means of wind energy extraction alongside conventional horizontal axis wind ...

Large Eddy Simulation of Vertical Axis Wind Turbine Wakes

Fernando Porté Agel, Sina Shamsoddin

In this study, large eddy simulation (LES) is combined with a turbine model to investigate the wake behind a vertical-axis wind turbine (VAWT) in a three-dimensional turbulent flow. Two methods are used to model the subgrid-scale (SGS) stresses: (a) the Sm ...
