OC5 task II simulations with FloaWDyn numerical model

Abstract

A 3D aero-hydro-servo-elastic coupled finite element method (FEM) numerical model in time domain for structural analysis has been developed at the UPC-BarcelonaTech (FloaWDyn). The code integrates the environmental forces from the waves and currents as well as the aerodynamic loads, including the wind turbine, and the mooring system. As a part of the FloaWDyn numerical code validation, in the paper is presented the calibration of the numerical model accordingly to the DeepCwind experimental scaled model, as well as some simulations of the Phase 2 of the OC5 project, which include the free decay tests and some coupled wind and waves tests. The simulations are finally compared to the results obtained in the experimental campaign at MARINTEK.
