Abstract
In the recent years an increasing interest has been devoted to the study of the
feasibility and relevance in combining wave energy converters with coastal structures. The present
work addresses the evaluation by numerical simulation of the extreme loads acting on a flap-type
energy converter. To this aim the SPH model can be an optimal candidate: its Lagrangian character
allows for an accurate description of the extreme breaking wave acting on the structure while its
meshless feature permits an easy interaction of the fluid with moving rigid bodies such as the
rotating flap converter. As a first approach, extreme wave characteristics have been computed
using statistical offshore wave elevation data. Then, the wave has been generated in a 2D
numerical wave tank through a piston wave- maker. Loads on the flaps are computed and
analysed considering a moving or fixed flap. A sensitivity analysis of the results has been
performed considering different impact dynamics (e.g. wave impact occurring before or after wave
breaking). The most critical cases found in the 2D analysis have been reproduced with a fully 3D SPH model.
