Abstract
In this study, the effects of wave-current interaction on a submerged cylindrical wave energy converter (WEC) are investigated using a two-dimensional, fully nonlinear numerical wave tank (NWT). The present NWT is first validated through simulating a wave-current interaction problem. It is then applied to study the performance of a submerged cylindrical WEC that is experiencing both waves and currents. To distinguish the effect of currents, the performance of the same WEC in pure waves is also evaluated as a benchmark. Both the effects of wave steepness and the speed of steady current on the efficiency of the WEC are investigated. It is found that the wave steepness has a slight influence while the speed of steady current can affect the efficiency substantially.
