Aerodynamic optimization of wind farm layout is a crucial task to reduce wake effects on downstream wind turbines, thus to maximize wind power harvesting. However, downstream evolution and recovery of wind turbine wakes are strongly affected by the charact ...
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 ...
In this work, we present the SmartBridge, a novel bridge section model equipped with actively controlled arrays of flaps aiming at mitigating wind-induced vibrations of long-span bridges. The active model, as well as its support structure, is described in ...

As the number of operating offshore large wind farms continues to increase, it is important to investigate the wake flows of these large wind farms since they could significantly affect the atmospheric boundary layer (ABL) dynamics and the performance of a ...

Wind LiDARs are nowadays a standard tool for the estimation of wind resource because of their ability to measure wind profiles, their reduced cost, the flexibility of their deployment and their ease of use. They allow the measurement of the horizontal wind ...

Inside wind farms, the wakes of upwind turbines result in a significant reduction in power production. Yawing upwind turbines can be used to deflect the wakes away from turbines. Even though this reduces the power production of upwind turbines, it can pote ...

We consider the problem of dispatching wind farm (WF) power demand to individual wind turbines (WTs) with the goal of minimizing mechanical stresses. We assume that wind is strong enough to let each WTs produce the required power and propose different clos ...
