Abstract
In this paper we present and discuss the use of CFD for coupled mooring analysis of floating wave energy converters. We use the two-phase Navier-Stokes finite volume solver in OpenFOAM and a high-order finite element model for the cable dynamics. The implementation of the coupling is described in some detail and we show validation of the scheme against laboratory data. A comparison between RANS and Euler simulations isolates effects of viscosity and geometric scale for moored point-absorbers, and parametric pitch excitation is demonstrated. The inclusion of power take-off/control follow the same blueprint as the mooring restraint and we illustrate the use of phase control.
