Large-Eddy Simulation of Wind-Turbine Wakes: Evaluation of Turbine Parametrisations

High turbulence levels promote wake recovery, through turbulent kinetic energy flux (entrainment), however how individual coherent structures contribute to wake recovery, is still

The test case of a BO105 helicopter crossing the NREL5 wind turbine wake was implemented in NLR’s Helicopter Pilot Station (HPS) simulator facili- ty, and was used

Et tu contemples ces vastes cieux Toute ta vie s'est passée dans la gloire De voir ton cœur doux comme ce soir De te relier avec tout ce qui fait un

al., 2011] we put forward the argument that the non-perturbed days were a result of lack of influence of wind turbines justified by the low frequency power law (cross- diagonal

New strategies such as involving wind turbine yaw angle seem relevant to reduce wake interaction and associated power losses 1.. Therefore, yawed turbine aerodynamics is modified

According to the electrical power curves, the power produced by the WT using the nonlinear dynamic state feedback with a wind speed estimator (NDSFE), clearly shows better

The framework starts by randomly sampling mean wind speed data from its probability density function (PDF), that is fed an inflow model (TurbSim), resulting in random

Previous investigations of tilt control have mostly considered the effect of tilting rotors of upwind turbines in an isolated column of aligned turbines; for the case of two
