Boon, D.J. (author), Dwight, R.P. (author), Sterenborg, J.J.H.M. (author), Bijl, H. (author)We perform a fully stochastic analysis of an experiment in aerodynamics. Given estimated uncertainties on the principle input parameters of the experiment, including uncertainties on the shape of the model, we apply uncertainty propagation methods to a suitable CFD model of the experimental setup. Thereby we predict the stochastic response of...conference paper 2012

Sterenborg, J.J.H.M. (author), Van Zuijlen, A.H. (author), Bijl, H. (author)In order to validate fluid-structure interaction solvers, a one degree of freedom (1 DOF) aeroelastic experiment is performed. A rigid wing with an harmonically actuated flap, is suspended by springs to allow a free heaving motion. Displacements and time dependent aerodynamic forces are measured for reduced flap frequencies ranging from k = 0.1...conference paper 2011

Lindeboom, R.C.J. (author), Sterenborg, J.J.H.M. (author), Simao Ferreira, C.J. (author)The unsteady flow conditions experienced by wind turbine blades lead to fatigue loads due to gusts, that increase the cost of energy. The decrease of the impact of these unsteady loads will most certainly lead to a decrease of the cost of energy. In order to alleviate unsteady loads the Smart Rotor Blade approach [2] applies spanwise-distributed...conference paper 2010
