Fluid–structure interaction simulations of a wind turbine rotor in complex flows, validated through field experiments

Abstract Aeroelastic simulations of a 2.3 MW wind turbine rotor operating in different complex atmospheric flows are conducted using high fidelity fluid–structure interaction (FSI) simulations. Simpler blade element momentum (BEM) theory based simulations are likewise conducted for comparison, and m...
