Wind farm and environmental aerodynamics assessment using computational engineering [PDF]
The aim of this thesis is the application of computational engineering software for the study of wind resource assessment of a wind farm as well as for establishing the range of influence of different numerical and physical parameters, including ...

Abstract Low‐level jets (LLJs)—wind speed maxima typically occurring a few hundred meters above the surface—are common off the U.S. East Coast and influence many atmospheric processes with societal importance, including cloud formation, aviation safety, and search‐and‐rescue.

Large Eddy Simulations of Energy Entrainment in Wind Turbine Wakes and Wind Farms [PDF]
Wind turbines extract kinetic energy from the inflow, leaving a wake region behind the turbine which has a lower velocity and higher turbulence intensity than the freestream. When turbines are clustered into wind farms, this leads to a reduction in power

Evaluating the Prediction of Wind Power Ramping Events in the Belgian Offshore Zone
This work proposes a flexible verification framework to assess wind power ramp forecasts more comprehensively than standard metrics. Applied to the Belgian Offshore Zone, it demonstrates the effectiveness of Wind‐Farm‐Parameterization and machine learning models and indicates a strong link between severe precipitation and predictable ramp events ...

Accounting for nonstationarity in the condition monitoring of wind turbine gearboxes [PDF]
Increasing growth of wind turbine systems suggests a more systematic research around their design, operation and maintenance is needed. These systems operate under challenging enviromental conditions and failure of some of their parts, for the time being,

Abstract High nature value (HNV) pastoral systems, that is those maintained by herding, transhumance and extensive grazing practices, are recognised as cornerstones of European biodiversity, cultural heritage and ecosystem service provision. Yet these systems are currently under significant pressure from a range of economic, social and environmental ...

Unsteady wake modelling for tidal current turbines [PDF]
The authors present a numerical model for three-dimensional unsteady wake calculations for tidal turbines. Since wakes are characterised by the shedding of a vortex sheet from the rotor blades, the model is based on the vorticity transport equations.

Sparsity Applications for Gradient‐Based Optimization of Wind Farms
ABSTRACT Optimizing wind farms is essential for designing efficient energy systems, especially as farms grow larger and span multiple sites. However, this optimization becomes increasingly challenging due to the rising computational cost associated with more turbines.

The wake structure of a wind turbine - comparison between PIV measurements and free-wake calculations [PDF]
Rotor aerodynamic prediction codes remain inaccurate, as many of the features of the wake flow are not yet fully understood, or are simply unknown. In the present work, this problem has been addressed by comparing the results of a sophisticated free-wake

Assessing the Underwater Impact of Aerodynamic Noise From Offshore Wind Turbines
ABSTRACT The growing demand for offshore wind energy has led to a significant increase in wind turbine size and to the development of large‐scale wind farms, often comprising 100–150 turbines. However, the environmental impact of underwater noise emissions remains largely unaddressed.
