In order to improve the wave energy capture rate of buoy a generation device, this paper proposes multi-degree freedom method optimize shape with maximum capture. Firstly, converter was designed, and defined using B-spline curve generate vector; then, numerical model established calculations were carried out AQWA/WEC-Sim software; on basis, particle swarm optimization algorithm introduced find corresponding Finally, in irregular waves. The results show that as increased, tended be flatter,...

This paper introduces a new point-absorber wave energy converter (WEC) with moonpool buoy—the platform (MPWEC). The MPWEC structure includes cylinder buoy and Power Take-off (PTO) system, where the relative movement between cylindrical is exploited by PTO system to generate energy. A 1:10 scale model was physically tested validate numerical further prove feasibility of proposed system. motion responses power absorbed studied in tank experiments were also numerically analyzed, potential...

In this work the hydrodynamic performance of a novel wave energy converter configuration was analytically and numerically studied by combining moonpool buoy, called platform–wave buoy (MP–WEB). A potential flow, semi-analytical approach adopted to assess total (incident, diffraction, radiation) forces acting on device, capture efficiency assessed, both in time frequency domain. The two configurations, single float double float, were analyzed compared terms diffraction force, added mass...

Abstract An array of floating point-absorbing wave energy converters (WECs) is usually employed for extracting efficiently ocean energy. For deep water environment, it more feasible and convenient to connect the absorbers with a body, such as semi-submersible bottom-moored disk, whose function act virtual seabed. In present work, an identical symmetrically distributed cylinders in coaxial moored disk device proposed The power take-off (PTO) system assumed be composed linear/nonlinear damper...

It is rather challenging to collect ocean wave energy at high efficiency because of its ultra-low frequencies and variable amplitudes. Triboelectric Nanogenerator (TENG) technology more suitable for harvesting low-frequency than electromagnetic power generation technology. In this work, we designed a built-in cylindrical (C-TENG) installed inside the buoy (BUOY-41). The hydrodynamic properties C-TENG are consistent with buoy, which calculated by CFD software (Star-CCM+). Energy Capture...
