Influence of hydrodynamic interactions on the productivity of PeWEC wave energy converter array

The deployment of multiple Wave Energy Converters in wave farms is the necessary step for wave energy to become competitive with respect to the other renewable energy sources. The numerical simulation of such arrays is complex because of the interaction among the devices, especially for converters characterized by multiple degrees of freedom. In this paper, the influence of two PeWECs (Pendulum Wave Energy Converters) is analyzed, at different positions with respect to the incoming waves. The perturbed wave field and the productivity of the array is investigated in comparison to the single device case in several configurations.
