Numerical Modelling of OWC-Shoreline Devices Including the Effect of Surrounding Coastlien and Non-Flat Bottom

摘要

In the numerical modelling of wave energy plants of the Oscillating Water Column (OWC) type, it is usual to consider the structure isolated and standing on an horizontal bottom. However when dealing with inshore devices, located in a non flat bottom, the geometry of the surrounding shoreline may have a strong influence on the behaviour of the OWC system, in what concerns the resonance frequencies and the hydrodynamic coefficients. the purpose of this work is the application of a 3D radiatondiffraction numerical code to the Azores European Pilot plant in the Island of Pico, taking into account the effect of the surrounding bathymetry and topography. The hydrodynamic problem is formulated in the frequency domain based on classical linear water wave theory. The present paper is an extension of a previous one (Brito-Melo et al., 1999).
