Analysis of a two-body floating wave energy converter with particular focus on the effects of power-take off and mooring systems on energy capture
International audience The present paper summarizes analyses of a two-body floating wave energy converter (WEC) including the mooring system. An axi-symmetric Wavebob type WEC is chosen as the object of investigation here. However, the PTO system is modeled in a simplified manner as ideal linear dam...
