.... The inherent unsteady and three-dimensional (3D) aerodynamics of vertical axis wind turbines (VAWT) have hitherto limited the research on wake evolution. In this paper, the wakes of both a troposkien and a H-type VAWT rotor are investigated by comparing experiments and calculations. Experiments were carried...

... at a standard implementation of a Beddoes Leishman type [ 33 ] unsteady aerodynamics model like that provided by Wendler et al. [ 34 ], we can see that the treatment of very deep or massive stall is not specifically treated. So, if the wind turbines are being subjected to vortex-induced vibrations, we could...
