Viscous Damping Identification for a Wave Energy Converter Using CFD-URANS Simulations
Journal of Marine Science and Engineering, 2020 During the optimization phase of a wave energy converter (WEC), it is essential to be able to rely on a model that is both fast and accurate. In this regard, Computational Fluid Dynamic (CFD) with Reynolds Averaged Navier–Stokes (RANS) approach is not ...
