| Research Abstract |
Our research is related to R&D of a floating wave energy converter system with multiple columns. The structure has OWC columns and buoyancy ones under deck structure. Wave tank test was performed to investigate the primary energy conversion efficiency of a single wave energy converter unit with circular cylindrical OWC column. We have developed a numerical analysis tool for estimating the energy conversion efficiency using eigen-functionexpansion method based on potential theory for waves. The calculated results was compared with the experimental ones and showed good agreement. We also performed wave tank test to investigate the interaction between OWC columns and buoyancy ones. The experimental results showed that the multiple OWC columns produce larger energy conversion and larger primary conversion efficiency. Furthermore we established the numerical method to estimate the interaction effect.
