Numerical Investigation of Focused Wave Impacts on Floating Wave Energy Converters Using OpenFOAM
MetadataShow full item record
This work concerns focused wave interactions with floating structures and represents an individual contribution to the CCP-WSI Blind Test Series 3, in which the submitted results are compared against both physical and alternative numerical solutions for varying wave steepness. The present numerical results are obtained using open-source CFD with waves generated via linear superposition of first order wave components, derived from empty tank data. Two geometries are considered and the effect of wave steepness on surge, heave and pitch motion, along with the load in the mooring, is examined. A `blind' estimation of error is presented, thought to be 10% or less in peak motion and mooring loads.
