ABSTRACT This paper presents an overview of the CONFLOWS project, a collaborative effort between DNV, Marine Power Systems (MPS) and Durham University. The project investigates the effects of wake steering from aerodynamic, structural and economic modelling perspectives, aiming to provide a comprehensive understanding of its impact on performance and ...

ABSTRACT In time‐marching dynamical simulations, treatment of contact forces in deformable bodies represented by finite element meshes requires a compromise between simulation fidelity and computational costs. External forces directly evaluated at the mesh nodes offer better computational performance at the cost of modelling fidelity.

2-D CFD Computations of the Two-Bladed Darrieus-Type Wind Turbine
In spite of the attractiveness of CFD methods and advanced measurement methods, there is still no full analysis of aerodynamic blade loads for vertical axis Darrieus-type wind turbines.

Improvements to tilt rotor performance through passive blade twist control [PDF]
A passive blade twist control is presented in which the twist distribution of a tilt rotor blade is elastically changed as a function of rotor speed. The elastic twist deformation is used to achieve two different blade twist distributions corresponding ...

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces
