Abstract:

The large wind turbine blades, while enhancing the efficiency of wind energy capture, inevitably lead to more complex nonlinear aeroelastic problems. This work aims to establish a nonlinear aeroelastic model for wind turbine blades by coupling strain-based beam with rotational effects and finite-state inflow theory with Prandtl tip loss correction. Numerical studies were conducted on a real blade model and compared with measured data.
