Effect of hills on the development of the wake of wind turbines

What is it about?

In the present work, the wake development behind small‐scale wind turbines is studied when introducing local topography variations consisting of a series of sinusoidal hills. The scale of the wind‐turbine models was about 1000 times smaller than full‐size turbines. Wind‐tunnel measurements were made by means of stereoscopic particle image velocimetry to characterize the flow velocity in planes perpendicular to the flow direction.
