Comparison and Validation of Hydrodynamic Theories for Wave Energy Converter Modelling

Creator:: Leary, Matthew M.
Abstract:: A wide variety of hydrodynamic theories are utilized to approximate a Wave Energy Converter’s (WEC) equation of motion. Numerous theories have been refined in order to improve numerical approximations of WEC dynamics. When incorporating refined hydrodynamic theories into numerical models, there are distinct impacts on WEC rigid body motions, cable...

Hydrodynamic characterization of floating offshore wind turbines : an experimental and numerical multi-degree of freedom analysis

Creator:: Gadasi, Jonah B.
Abstract:: Wind energy has become a crucial resource in sustainably meeting increasing global energy demands. Recently, offshore wind energy has been gaining traction due to its higher gross resource and larger unclaimed real-estate relative to its onshore counterpart. Floating offshore wind turbines (FOWTs) are increasingly popular, particularly designs with semisubmersible platforms....

Hydrodynamic Modeling of Submerged Wave Energy Converters: Power Take-Off Mooring Configuration Effect on Power Performance

Creator:: Meek, Moira H.
Abstract:: Wave energy converters (WECs) show promising potential to significantly contribute to global renewable energy goals. Numerous WEC designs have been proposed and investigated, but wave energy conversion technology has yet to reach convergence in the same way wind or solar has. Of the designs currently in existence, surface-piercing WECs are...
