Computational modeling of wind turbine wake interactions
The rapid expansion of the wind energy market necessitates the need for advanced computational modeling and understanding of wind turbine aerodynamics and wake interactions. The following thesis work looks to study turbulence closure methods widely used in computational fluid dynamics (CFD) and …

Dynamic wind turbine wake trajectory control: Strategies and real-time validation
Wind farm control has demonstrated power production enhancements using yaw-based wake steering. However, slower yaw actuation rates compared to inflow change rate cause time-varying downstream-rotor-wake overlap conditions, diminishing its benefits. To accommodate for inflow variations, closed-loop …

The effect of dynamic operation and incoming flow on the wake of a utility-scale wind turbine
Wind turbine wakes, the regions of slower and more turbulent air behind turbines, lead to power losses up to 40% and increased structural loading on downwind turbines within a wind farm. To mitigate these detrimental effects, improved understanding of wake behavior is required. However, modeling …

Optimization of Wind Turbine Airfoils/Blades and Wind Farm Layouts
… optimization is widely used in the design of wind turbine blades. In this dissertation, a numerical optimization method called Genetic Algorithm (GA) is applied to address the shape optimization of wind turbine airfoils and blades. In recent years, the airfoil sections with blunt trailing edge …

Caracterización numérica de la turbulencia en el estela de una aeroturbina mediante un modelo de simulación de grandes escalas
… con datos experimentales de este tipo. ABSTRACT Wind turbine wakes are an interesting topic of study. Velocity defects and the increase of turbulence generated by the turbines in a wind farm usually cause a reduction in power generation and unsteady loads over other machines. In wind farms where, …

Unsteady separation control on wind turbine blades
… one of the primary causes of unsteady loads on wind turbine blades. The process can be instigated by a multitude of factors, common in wind turbine operating environments, such as inflow turbulence, wind gusts and sustained yaw misalignment. The unsteady separation due to dynamic stall can lead …
