Stability of Floating Wind Turbine Wakes

Journal of Physics: Conference Series, 2021
Abstract Floating offshore wind turbines (FOWTs) are the next frontier in offshore wind energy, allowing exploration of deep-water regions previously unavailable to fixed-foundation turbines. Since offshore turbines operate in lower turbulence levels, the intrinsic hydrodynamic unstable modes of the tip vortices can have even more ...

A Nonlinear Computational Model of Floating Wind Turbines

Journal of Fluids Engineering, 2012
The dynamic motion of floating wind turbines is studied using numerical simulations. The full three-dimensional Navier–Stokes equations are solved on a regular structured grid using a level set method for the free surface and an immersed boundary method for the turbine platform.

Cascade Analysis of a Floating Wind Turbine Rotor

Journal of Physics: Conference Series, 2014
Mounting a wind turbine on a floating foundation introduces more complexity to the aerodynamic loading. The floater motion contains a wide range of frequencies. To study some of the basic dynamic load effect on the blades due to these motions, a two-dimensional cascade approach, combined with a potential vortex method, is used.
