Overview

Simulation study demonstrates a 6.46% power gain and complex aeroelastic dynamics in floating vertical-axis wind turbines, highlighting improved modeling for offshore wind energy.

Key Points

To establish an integrated aero-hydro-elastic-mooring framework coupling computational fluid dynamics and finite element methods to predict the multi-physics performance of floating vertical-axis wind turbines.
Integrated computational fluid dynamics (CFD) and the finite element method (FEM) to model two-way fluid-structure interaction.
Simulated fully coupled turbine behavior under turbulent wind, ocean waves, structural elasticity, and seabed mooring line interactions.
Platform motion enhanced leading-edge vortices and dynamic stall, resulting in an approximate 6.46% increase in the mean power coefficient compared to a bottom-fixed turbine.
Platform-induced wake deflection and turbulent mixing accelerated wake recovery downstream, while flexible blades exhibited nonlinear bending-torsional deformations and localized stress concentrations.
Mooring lines experienced periodic contact and detachment from the seabed, identifying critical areas for potential scour and fatigue accumulation.
