摘要：An array of floating point-absorbing wave energy converters (WECs) is usually employed for extracting efficiently ocean wave energy.For deep water environment,it is more feasible and convenient to connect the absorbers array with a floating body,such as a semi-submersible bottom-moored disk,whose function is to act as the virtual seabed.In the present work,an array of identical floating symmetrically distributed cylinders in a coaxial moored disk as a wave energy device is proposed The power take-off (PTO) system in the wave energy device is assumed to be composed of a linear/nonlinear damper activated by the buoys heaving motion.Hydrodynamic analysis of the examined floating system is implemented in frequency domain.Hydrodynamic interferences between the oscillating bodies are accounted for in the corresponding coupled equations.The array layouts under the constraint of the disk,incidence wave directions,separating distance between the absorbers and the PTO damping are considered to optimize this kind of WECs.Numerical results with regular waves are presented and discussed for the axisymmetric system utilizing heave mode with these interaction factors,in terms of a specific numbers of cylinders and expected power production.
