Effect of winds in a mountain pass on turbine performance

Mountain passes are potentially advantageous sites for the deployment of wind turbines because of road links and electrical transmission infrastructure. However, relatively little is known about wind characteristics and turbine response in these environmen ...

Mean and turbulent kinetic energy budgets inside and above very large wind farms under conventionally-neutral condition

Fernando Porté Agel, Mahdi Abkar

In this study, large-eddy simulations (LES) is combined with a turbine model to investigate all the terms in the budgets of mean and turbulent kinetic energy (TKE) inside and above very large wind farms. Emphasis is placed on quantifying the relative contr ...

Field Measurements of Wind Turbine Wakes with Lidars

Fernando Porté Agel, Giacomo Valerio Iungo, Yu-Ting Wu

Field measurements of the wake flow produced from a 2-MW Enercon E-70 wind turbine were performed using three scanning Doppler wind lidars. A GPS-based technique was used to determine the position of the wind turbine and the wind lidar locations, as well a ...

A Large Eddy Simulation Study for upstream wind energy conditioning

Varun Sharma, Marc Parlange, Marc Calaf Bracons

The wind energy industry is increasingly focusing on optimal power extraction strategies based on layout design of wind farms and yaw alignment algorithms. Recent field studies by Mikkelsen et al. (Wind Energy, 2013) have explored the possibility of using ...

Linear stability analysis of wind turbine wakes performed on wind tunnel measurements

Fernando Porté Agel, François Gallaire, Giacomo Valerio Iungo, Francesco Viola

Wind tunnel measurements were performed for the wake produced by a three-bladed wind turbine immersed in uniform flow. These tests show the presence of a vorticity structure in the near-wake region mainly oriented along the streamwise direction, which is d ...

Wind-Turbine Wakes in a Convective Boundary Layer: A Wind-Tunnel Study

Fernando Porté Agel, Wei Zhang, Corey Dean Markfort

Thermal stability changes the properties of the turbulent atmospheric boundary layer, and in turn affects the behaviour of wind-turbine wakes. To better understand the effects of thermal stability on the wind-turbine wake structure, wind-tunnel experiments ...

Disposable 600-mL orbitally shaken bioreactor for mammalian cell cultivation in suspension

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Dominique Terry Monteil Jr, Saroj Ghimire, Giulia Tontodonati

Orbitally shaken bioreactors (OSRs) support the efficient cultivation of mammalian cells in suspension at various scales of operation. Here we introduce a disposable culture vessel with a ventilated cap having a nominal volume of 600 mL (TubeSpin (R) biore ...

Current variability in a wide and open lacustrine embayment in Lake Geneva (Switzerland)

David Andrew Barry, Alfred Johny Wüest, Ulrich Lemmin, Roham Bakhtyar, Amir Mehdi Razmi, Nicolas Le Dantec

Field measurements and numerical simulations were used to determine the effects of dominant meteorological conditions on the hydrodynamics of a wide (aspect ratio ~2), relatively deep (seasonally stratified) and open lake embayment (Vidy Bay, Lake Geneva). ...

Optimal Storage Policies with Wind Forecast Uncertainties

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Nicolas Gabriel Gast

The increase in penetration of wind in the current energy mix is hindered by its high volatility and poor predictability. These shortcomings lead to energy loss and increased deployment of fast ramping generation. The use of energy storage compensates to s ...

Quasi-stationary optimal control for wind farm with closely spaced turbines

Tomislav Horvat, Mahsa Parsapour

Modern wind farms typically comprise a large number of wind turbines spread on a relatively small area. The closely spaced turbines are aerodynamically coupled since they share the common energy resource. The aerodynamical coupling is described by the wake ...
