Simulation of fluid impact with an ocean wave energy convertor and evaluation of its operation

Ocean waves are one of the energy resources that haspotential to fulfill some parts of the world’s energyrequirements and reduce the need for fossil fuels andother forms of nonrenewable energies. The wave energycan be converted to the high quality energies such aselectricity. Recently, existing ocean wave energyconversion (OWEC) devices have been evaluated to findthe most appropriate system for the wave energyextraction in the Caspian Sea. Point absorbers are foundto be the most appropriate device for this sea.This study aims to evaluate one of the newest pointabsorber devices that would be capable of being used inCaspian Sea. Thus, this study presents a numerical modelfor a point absorber device in a wave tank using acommercial CFD code, Flow-۳D. The ReynoldsAveraged Navier-Stokes in coupled with VOF model areutilized to generate the ۳D numerical linear propagatingwaves. The most important parameters of point absorberincluding water flow rate in different seasons, extractablewave power, and output power of the device werecomputed.
