Outline of Final Research Achievements

Oscillating Water Column (OWC) type wave energy converter "Back bending duct buoy (BBDB) has superior properties of small size, small mooring force, high efficiency.
In this research, we developed a new optimum design method that can consider floating motion in irregular waves, air pressure variation in air chamber, air turbine characteristics, mooring system characteristics at the same time. This technology contributes to a wave-energy farm consisting of many BBDBs.
