Geometry Effects of an Oscillating Wave Surge Converter on its Energy Absorption

In this study six different shapes for oscillating wave surge converter are introduced and their energy absorption in a specific wave is investigated. This research is done by numerical simulation of a typical wave flume that operates in six seconds and the transferred energy is absorbed by each OWSC. Due to using structured grid mesh, simulation of different shapes is fairly fast. The results show that geometry of OWSC plays a significant role in energy absorption. The effect of restoring force and power take off system is also investigated by considering the forces as a body force in numerical simulation.
