Resumen

A comparison is presented between wind tunnel (WT) and full scale (FS) measurements of spatial distributions of turbulence intensities, IUi = aUiS~1, and their ratios; U4 being the fluctuations of velocity components and S the mean velocity magnitude, over the Bolund hill. The Bolund experiment, conducted by Ris0-DTU during a 3-month period in the winter of 2007-2008, is probably the most relevant test case of flow models oriented to wind energy analysis, in this case, over highly complex terrains, in neutral conditions and non affected by Coriolis forces. The Bolund hill is a small peninsula, with an almost vertical 11 m height escarpment facing westerly winds, and a nearly flat plateau extending towards East. This geometry produces complex flow structures which are a challenge for numerical and wind tunnel simulations. The available results, since the end of the Bolund experiment, have mainly focused on the spatial distribution of the mean velocity magnitude and turbulent kinetic energy. Our interest is now in how the turbulent kinetic energy is distributed among the velocity components (what is relevant for wind turbine response), and to which extend our wind tunnel experiment (1:115 scale, 3CHotWire, 3CHW, and Particle Image Velocimetry, PIV) can reproduce these distributions.
