We provide an overview of the Arbitrary Lagrangian-Eulerian Variational Multiscale (ALE-VMS) and Space-Time Variational Multiscale (ST-VMS) methods we have developed for computer modeling of wind-turbine rotor aerodynamics and fluid-structure interaction (FSI). The related techniques described include weak enforcement of the essential boundary conditions, Kirchhoff-Love shell modeling of the rotor-blade structure, NURBS-based isogeometric analysis, and full FSI coupling. We present results from application of these methods to computer modeling of NREL 5MW and NREL Phase VI wind-turbine rotors at full scale, including comparison with experimental data.
