Large-eddy simulation of atmospheric boundary layer flow through wind turbines and wind farms

Accurate prediction of atmospheric boundary layer (ABL) flow and its interactions with wind turbines and wind farms is critical for optimizing the design (turbine siting) of wind energy projects. Large-eddy simulation (LES) can potentially provide the kind ...

Study of a Fully Developed Wind Turbine Array Boundary Layer

Marc Calaf Bracons

Wind harvesting is fast becoming an important alternative source of energy. As wind farms become larger, they begin to attain scales at which two-way interactions with the atmospheric boundary layer (ABL) must be taken into account. Several studies (Baidya ...

Models of wind-turbine main-shaft bearings for the development of specific lightning protection systems

Mario Paolone

One of the main causes of damages for wind-turbine power plants is lightning. Direct and indirect events, indeed, can produce damages and malfunctions of electrical and mechanical components. Concerning mechanical components, blades and bearings are the mo ...

Turbulent Flow Inside and Above aWind Farm: A Wind-Tunnel Study

Fernando Porté Agel

Wind-tunnel experiments were carried out to better understand boundary layer effects on the flow pattern inside and above a model wind farm under thermally neutral conditions. Cross-wire anemometry was used to characterize the turbulent flow structure at d ...

Large-eddy simulation of a very large wind farm in a stable atmospheric boundary layer

Fernando Porté Agel, Hao Lu

When deployed as large arrays, wind turbines significantly interact among themselves and with the atmospheric boundary layer. In this study, we integrate a three-dimensional large-eddy simulation with an actuator line technique to examine the characteristi ...

Decision Support System for the hydropower plants management : the MINERVE project

Anton Schleiss, Javier García Hernández

The MINERVE project was initiated for flood management in the Upper Rhone river basin. Its first goal is the prediction of floods. The second one is the optimum management of the complex system of hydropower plants located in the basin in order to diminish ...

Large eddy simulation study of fully developed wind-turbine array boundary layers

Charles Vivant Ignacio Meneveau, Marc Calaf Bracons

It is well known that when wind turbines are deployed in large arrays, their efficiency decreases due to complex interactions among themselves and with the atmospheric boundary layer (ABL). For wind farms whose length exceeds the height of the ABL by over ...
