Fluid–structure interaction modeling of wind turbines: simulating the full machine

In this paper we present our aerodynamics and fluid---structure interaction (FSI) computational techniques that enable dynamic, fully coupled, 3D FSI simulation of wind turbines at null scale, and in the presence of the nacelle and tower (i.e., simulation of the full machine). For the interaction of wind and flexible blades we employ a nonmatching interface discretization approach, where the aerodynamics is computed using a low-order...
