Abstract

The present research studies the impact of wave charactristics as well as the power take-off (PTO) damping on the hydrodynamic performance of a two-body floating point absorber (FPA) which sometimes called self-reacting point absorber (SRPA) or two-body wave energy converter (WEC) device. This type of WEC is designed for operation in the Gulf of Oman and its geometry is inspired from the famous reference model (RM3) which was developed at the National Renewable Energy Laboratory (NREL), United States. The numerical model was developed in the Siemens STAR-CCM+ software which solves the complete form of fluid governing equations. The parameters of the incident waves, was selected based on the previous researches on this region and PTO damping is specified based on the RM3 model design. The results show that changes in wave period and PTO damping significantly influence energy capture and converter efficiency. The results show that the absorbed power increases monotonically with wave height and reaches a maximum at a wave period of 6 s, indicating a clear resonant response of the two‑body WEC across all tested sea states.
