主　　题：cean wave energy Energy conversion Oscillating water column Multi-chamber OWC 

摘      要：Sea wave energy generators or converters(WECs)have the potential to become a viable technology for clean,renewable energy *** the WEC technologies,the oscillating water columns(OWCs)are the most common WEC devices *** have been studied and developed over many ***-chamber oscillating water columns(MC-OWC)have the potential to have a higher energy conversion when extracting energy in mixed sea states than single-chamber *** the work reported in this paper,physical experiments are carried under regular wave conditions to test the wave power extraction of a fixed MC-OWC small-scale *** Power Take-Off(PTO)of the device is simulated using orifice *** flow characteristics through these orifices are pre-calibrated such that the extracted power can be obtained only using the pressure *** condition effects on the damping of the PTO of the device power extraction are *** test results illustrate that the PTO system damping is critical and affects device performance.
