Performance Analysis of Multiple Wave Energy Converters due to Rotor Spacing

A numerical hydrodynamic performance analysis of the pitch-type multibody wave energy converter (WEC) is carried out based on both linear potential flow theory and computational fluid dynamics (CFD) in unidirectional condition. In present study, Salter’s duck (rotor) chosen for analysis. The basic concept WEC rotor, which nods when pressure-induced motions are phase, that it converts kinetic energies into rotational mechanical with proper power-take-off system. This converted to useful electric energy. using three rotors. performed WAMIT (three-dimensional diffraction/radiation program), a CFD by placing rotors tank. particular, spacing between set 0.8, 1, 1.2 times rotor width, interaction adjacent checked. Finally, confirmed dynamic slightly changes, but difference due not noticeable. addition, shows lateral phenomenon cannot be theory, necessary motion rotor.
