(TU Delft Wind Energy) De Oliveira Andrade, G.L. (TU Delft Wind Energy) Timmer, W.A. (TU Delft Wind Energy) Quaeghebeur, Erik (TU Delft Wind Energy) Date 2018 Abstract We describe a probabilistic approach to design airfoils for wind energy applications. An analytical expression is derived for the probability of perturbations to the operational blade-section angle of attack. It includes the combined influence of wind shear, yaw-misalignment, and turbulence intensity. The theoretical fluctuations in angle of attack are validated against an aero-structural simulation of a 10 MW horizontal axis wind turbine, operating under different inflow conditions. Finally we incorporate the probabilistic approach into a multi-objective airfoil optimization problem, which is solved with a genetic algorithm. The results illustrate the compromise between airfoil performance for a specific angle of attack and robustness of airfoil performance over a large range of angle of attack fluctuations To reference this document use: http://resolver.tudelft.nl/uuid:dab0e792-36c4-4a2a-923a-9edf0bd2c4b0 DOI https://doi.org/10.1088/1742-6596/1037/2/022042 ISSN 1742-6588 Source Journal of Physics: Conference Series, 1037 Event TORQUE 2018, 2018-06-20 → 2018-06-22, Milano, Italy Part of collection Institutional Repository Document type journal article Rights © 2018 R.
