Abstract

Wind turbines are expected to operate in environments where they could be subjected to turbulence and gusts in the incident flow. As such, there is a need to develop analysis methodologies for predicting variations in aerodynamic loads, their effects on structural performance and control strategies to limit the impact of these variations. The multidisciplinary nature of this problem and high cost of high fidelity simulations present the need to develop multi-fidelity numerical models for accurate prediction of the aerodynamic loads and structural response of rotating blades under different unsteady flow conditions. In this work, we implement a three-dimensional version of the unsteady vortex lattice method (UVLM) to simulate the aerodynamic response of a rigid rotating blade subjected to an incoming unsteady freestream. The unsteadiness effects are incorporated by adding a deterministic gust. Two different control strategies are implemented to reduce gust effects on the aerodynamic loads. The advantages of the two strategies are discussed.
