Abstract: Most of the wind turbines analysis studies have been conducted under steady and uniform wind conditions. The unsteady flow past rotating rotor blades is, however, one of the most challenging applications for a numerical simulation. This is attributed to the existing aerodynamic complexities under such conditions. In this paper, a numerical approach to investigate the global dynamic behaviour of a Darrieus turbine under unsteady and non-uniform flow conditions is proposed. The dynamic response of Darrieus wind turbine geared system operating in fluctuating inflow present a more significant challenge for this approach.
