Comparison of Power and Thrust Performance for a Fixed and Floating Offshore Wind Turbine
ABSTRACT Floating offshore wind turbines have been identified as a critical technology for sustainable electricity generation. Wind resource assessment is used to determine optimal locations for floating wind farms. However, current methodologies do not account for performance differences between fixed and floating turbines due to wind‐ and wave ...

Wind Tunnel Assessment of Dynamic Induction Control Under Varying Inflow Wind Directions
ABSTRACT Dynamic induction control (DIC), also known as pulse control, is a wake‐mixing strategy intended to improve wind farm efficiency by mitigating wake‐induced power losses. It typically employs harmonic collective blade pitching to excite wake instabilities, forming coherent pulsing structures that enhance turbulent mixing and accelerate wake ...

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading
ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

Development of a passive‐adaptive slat for a wind turbine airfoil
A passive‐adaptive slat concept was designed to avoid separation in the root region of a horizontal‐axis wind turbine blade. This concept incorporates an autonomously moveable slat device only driven by the aerodynamic forces acting on it without the ...

Modeling, Validation, and Control of the IEA‐15 MW Reference Wind Turbine and VolturnUS‐S Platform
ABSTRACT This paper presents the acausal modeling, validation, and control of floating offshore wind turbines (FOWTs). The model simulates the IEA‐15 MW reference turbine and the semi‐submersible VolturnUS‐S platform utilizing a Control‐oriented, Reconfigurable, and Acausal Floating Turbine Simulator (CRAFTS), which integrates the key coupled aero ...

ABSTRACT Yaw engineering models are commonly used as add‐ons to the industrial blade element momentum (BEM) framework to improve load and power predictions by accounting for the skewed wake effect. However, existing yaw engineering models show noticeable limitations in accurately predicting the induced velocity distribution across the blade span.
