    Abstract

    This paper investigates scaling laws that were adopted for the DeepCwind project for testing three different floating wind systems at 1/50 scale in a wave tank under combined wind and wave loading. The 1/50 scaling of the full-scale 5-MW wind turbine system is performed based on Froude scaling laws, which are commonly used for offshore structures. The scaling approach adopted is verified through FAST, an aero-hydro-servo-elasto dynamic modeling tool, by comparing the consistency of simulation results between model and full scale. The Froude scaling approach does not maintain proper Reynolds number scaling and the implications of this issue are discussed.
