Development of a nonlinear state space model of the forces acting on an aerofoil oscillating in pitch

In this article, we develop a nonlinear data-driven model of the aerodynamic force on an aerofoil made tooscillate in pitch in a wind tunnel under constant flow conditions. The proposed model structure is a polynomial nonlinear state-space model …

Wake predictions of full HAWT rotor and actuator disk model CFD simulations using different RANS turbulence models compared to experimental measurements

The development of large scale wind energy projects created the demand for increasingly accurate and efficient models that limit the project’s uncertainties and risk. Wake effects are of great importance and together with the complex terrain effects …
