Hydrodynamic modeling and optimization of mobile wave energy harvesting system for the robotic buoy

Abstract

The robotic buoy which is a mobile mooringless buoy and keeps position autonomously against ocean current.[1][2][3] The robotic buoy is specialized for operating on an environment where is too deep to anchor for mooring, like middle of an ocean. The robotic buoy is compose of two systems, propulsion system and energy harvesting system. ‘Wave Turbine’ is a PTO(Power take-off)[4] to harvest oceanic wave energy for the robotic buoy[1][2][3]. The improved hydrodynamic numerical analysis method was developed and verified to optimize the energy efficiency of the wave turbine. Then the optimized parameters were suggested by the simulation.
