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 ...

Springer Verlag2017

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 ...

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

Fernando Porté Agel, Sina Shamsoddin

2016

Systematic dependence on fossil fuels has led to high levels of carbon emissions. These emissions play a key role in exacerbating climate change. As the negative effects of climate change become more apparent, more resources are being invested into finding ...

Modeling turbine wakes and power losses within a wind farm using LES: An application to the Horns Rev offshore wind farm

Fernando Porté Agel, Yu-Ting Wu

A modeling framework is proposed and validated to simulate turbine wakes and associated power losses in wind farms. It combines the large-eddy simulation (LES) technique with blade element theory and a turbine-model-specific relationship between shaft torq ...

Effects of Positive versus Negative Yaw Angles on Wind-Turbine Performance: An Application of BEM Theory

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 ...

Influence of the Hydraulic System Layout on the Stability of a Mixed Islanded Power Network

François Avellan, Christophe Nicolet, Christian Landry, Stefano Giacomini

Numerical simulation and stability analysis of an islanded power network comprising 40 MW of hydropower, 20 MW of wind power and 60 MW of gas-fired power plant are investigated. First, the modeling of each power plant is fully described. The wind farm is m ...

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 ...
