Numerical Modeling of Floater Dynamics of a FOWT
For Wind Tunnel Hardware-in-the-Loop Testing
The goal of the research is to improve the fidelity of the TUDelft HIL numerical simulation by developing a higher fidelity mooring line model, both quasi-static and dynamic formulations. Furthermore, second-order wave excitation forces are included using Newman's Approximation to more accurately model the sea state. This implementation is verified versus OpenFast simulations. The improved model is then tested in the OJF windtunnel to test the different models and compare between them. Here combined wind-wave action are tested for a range of operating conditions. The effects of second-order forces are quantified, as well as the effects of aerodynamic loads on the motion of the system. Finally, a fundamental study is done on the aerodynamic damping at a range of wind speeds, in surging, pitching and yawing motion.
