We have investigated the wind turbine and two-dimensional wing performance in various fluctuating flows including pulsating flows and turbulent flows with different intensities and scales. As a result, the power outputs of the wind turbine in pulsating flows shows higher values compared to those in smooth steady flows. For a certain condition of turbulent flows, the power output of wind turbine show a higher value than those in smooth and other turbulent flows. In addition, the wing performance improved by turbulence, and the flow around the wing has changed by roughness. Therefore, the possibility that the turbulence with small scales can make an interference with the boundary layer around a turbine blade and improve lift performance is shown.
