Numerical Modelling of Double Slit Caisson Breakwater Integrated Oscillating Water Column Wave Energy Converter with Modal Superposition Method

Oscillating water column wave energy converter is a power generation device in which ocean waves excite the oscillation of surface an air chamber, generates fluctuations pressure and rotate turbine generator(s). The fluid chamber phenomenon with natural period, similar to container such as sloshing. Previous research has shown that for oscillating single submerged water, characteristics can be modeled one-degree-of-freedom system takes only mode into account. However, double-slit breakwater integrated using two columns separated by slit walls, been verified have resonance periods. In this study, free motion modal superposition method including first-order second-order modes vertical surfaces. result from simulation vibration experiment.
