Assessing the Underwater Impact of Aerodynamic Noise From Offshore Wind Turbines

Wind Energy, Volume 29, Issue 7, July 2026.
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.

Parametric research and aerodynamic performance analysis of wind turbine airfoil with added flap

AIP Advances, 2022
A self-popped up flap is added to the airfoil (S809) suction surface to improve aerodynamic performance under large angle of attack (AOA) inspired by the slightly popped up feathers on the trailing edge of a bird’s wing. The response surface methodology (

Multipoint Aerostructural Optimization of Wind Turbine Rotors Using a Coupled Blade‐Resolved Aerostructural Solver

Wind Energy, Volume 29, Issue 7, July 2026.
ABSTRACT Physics‐based design optimization workflows thread the needle between computational cost limitations and simulation complexity, often compromising between modeling detail and the range of operating design conditions. Multipoint aerostructural optimization of wind turbine rotors has so far been confined to low‐fidelity analyses or to high ...

Design space dimensionality reduction through physics-based geometry re-parameterization

, 2013
The effective control of the extent of the design space is the sine qua non of successful geometry-based optimization. Generous bounds run the risk of including physically and/or geometrically nonsensical regions, where much search time may be wasted ...

Numerical optimization for high efficiency, low noise airfoils [PDF]

29th AIAA Applied Aerodynamics Conference, 2011
One key element in the aerodynamic design of wind turbines is the use of specially tailored airfoils to increase the ratio of energy c apture to the loading and thereby to reduce cost of energy. At the same time, noise reduction i s becoming more and more important.
