Abstract
The Oscillating Water Column (OWC) appears as a suitable Wave Energy Converter (WEC) to be integrated to port and coastal structures (e.g. the EMACOP project). A particular attention should be paid to the influence this device could have on hydrodynamics, sediment transport and morphological evolutions. This paper proposes preliminary results of a 2D Navier-Stokes numerical modelling in the vicinity of an OWC, focusing on key hydrodynamic processes: wave propagation, wave bottom boundary layer and wave/device interaction. In order to determine optimal conditions and configuration of such an approach for real case applications, a parametric study is carried out for each of the hydrodynamic processes at work. The results from this parametric study are discussed and compared to wave flume measurements and other existing numerical simulations.
