This paper presents the results of laboratory tests on a hybrid wave energy converter concept, O2WC (Oscillating-Overtopping Water Column) device. The proposed device aims at providing an alternative to classical OWC storing part highly energetic sea states in second chamber atmospheric pressure, through overtopping phenomena. In this way, maximum airflow rate and air pressure are reduced, poss...

Wind effects on wave overtopping over a fully impermeable vertical sea wall were studied numerically using the open-source computational fluid dynamics library OpenFoam. A pressure gradient correction term was incorporated in momentum equations. In recent studies, it found that, absence of wind, an increase steepness results reduction overtopping. This is related to instability standing formed ...
