Nonlinear beam element in HAWC2 for modeling of mooring systems

max. 2000 char.): This report contains the slides of the presentations at the Aeroelastic Workshop held at Risø-DTU for the wind energy industry in Denmark on January 27, 2011. The scientific part of the agenda at this workshop was • Anisotropic beam element in HAWC2 for modelling of composite lay-ups (Taeseong Kim) • Nonlinear beam element in HAWC2 for modelling of mooring systems (Bjarne Kallesøe) • Enhanced BEM including wake expansion and swirl (Christian Bak) • Unsteady viscous-inviscid interactive airfoil code for wind turbines (Néstor Ramos García) • PIV measurements on model scale wind turbine in water channel (Robert Mikkelsen) • Potential of fatigue and extreme load reductions on swept blades using HAWC2 (David Verelst) • Aeroelastic modal analysis of backward swept blades using HAWCStab2 (Morten H. Hansen) • Aeroelastic rotor design minimizing the loads (Christian Bak) • A small study of flat back airfoils (Niels N. Sørensen) • Status of airfoil design and plans for wind tunnel tests of new thick airfoils (Christian Bak) The presented results are mainly obtained in the EUDP project “Aeroelastic Optimization of MW Wind Turbines (AeroOpt)” funded under contract no. 63011-0190.
