A semi-analytical model for velocity profile at wind turbine wake using blade element momentum
Authors
Abstract:
The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. The present study calculated a semi-analytical profile for the shape of the wake behind a wind turbine using blade element momentum method. It is shown that the wake shape differs in different operational conditions and geometrical characteristics of the wind turbine.

full textA robust engineering approach for wind turbine blade profile aeroelastic computation
Wind turbines are important devices that extract clean energy from wind flow. The efficiency of wind turbines should be examined under various working conditions in order to estimate off-design performance. Numerous aerodynamic and structural research works have been carried out to compute aeroelastic effects on wind turbines. Most of them suffer from either the simplicity of the modelling appr...

full textA Model for Wind Turbine Blade with Enhanced Torsional Stability
A mathematical model for enhancing the torsional stability of a slender, tapered, composite wind turbine blade is presented. The increase of the stability boundary is measured by maximization of the critical wind speed at which failure may occur by aeroelastic divergence in parked-turbine state. The total structural mass of the blade is kept constant in order not to violate other economic and p...
