The majority of existing WECs (wave energy converters) are designed to achieve maximum power at a resonance condition. In thecase of a single WEC, its size must be large enough for tuning, and it has high efficiency only within a limited frequency band. Recently, wavepower extraction by deploying many small buoys in a compact array has been studied under the assumption that the buoy's size and separationdistance are much smaller than the water depth, wave length, and size of the array. A boundary value problem involving the macro-scale boundarycondition on the mean surface covered by an infinite strip of buoys is solved using the eigenfunction expansion method. The energy extractionefficiency (ε=1-R2f-T2r), where Rf and Tr are the reflection and transmission coefficients for a strip array of buoys, is assessed for variouscombinations of packing ratio, strip width, and PTO damping coefficient.
Abstract
The majority of existing WECs (wave energy converters) are designed to achieve maximum power at a resonance condition. In thecase of a single WEC, its size must be large enough for tuning, and it has high efficiency only within a limited frequency band. Recently, wavepower extraction by deploying many small buoys in a compact array has been studied under the assumption that the buoy's size and separationdistance are much smaller than the water depth, wave length, and size of the array. A boundary value problem involving the macro-scale boundarycondition on the mean surface covered by an infinite strip of buoys is solved using the eigenfunction expansion method. The energy extractionefficiency (ε=1-R2f-T2r), where Rf and Tr are the reflection and transmission coefficients for a strip array of buoys, is assessed for variouscombinations of packing ratio, strip width, and PTO damping coefficient.
