Comparison of Aero-Elastic Simulations and Measurements Performed on NENUPHAR’s 600kW Vertical Axis Wind Turbine: Impact of the Aerodynamic Modelling Methods: Paper

Aero-elastic solver predictions are compared to measured data from the NENUPHAR’s 1HS prototype, with a focus on the blade loads. Two solvers are investigated, namely the HAWC2 solver, and DeepLinesWindTM, respectively based on a linear and a non-linear formulation of the Timoshenko beam theory. Various aerodynamic models are used, from simple Multiple Streamtube models up to the Actuator-Cylinder flow model and 2D/3D Vortex flow solvers.

A special attention is also given to the influence of the dynamic stall on the results. Aero-elastic solvers predictions are accurate and fit well with the measured blade loads, but this work emphasizes the fact that suitable aerodynamic model and stall model should be used.
