The fluid-dynamic simulation of wind turbine aerodynamics is typically tackled by applying multi-fidelity computational tools. In this context, the so-called actuator line model combines a low-fidelity treatment rotor with high-fidelity resolution wake. paper, novel formulation proposes vortex-based method to sample flow around rigorously assign forces imparted blades. This new technique implemented into an in-house code developed within OpenFOAM environment, and it validated against wind-tunnel experiments on laboratory-scale horizontal-axis operated in fixed-bottom floating conditions. calculations are also compared simulations performed, same test case, frame OC6 Phase III project. results, obtained after systematic analysis selection parameters, exhibit remarkable agreement available place present proper ranking fidelity levels, in-between momentum-balance methods blade-resolved CFD models. Finally, for surge pitch platform motions demonstrate capability proposed reliably predict rotors dynamic operation at affordable cost.
