Comparison of full scale and wind tunnel measurements of the spatial distribution of turbulence components over the Bolund Island

摘要

We present experimental spatial distributions of turbulence intensity components over a 1:115 scale model of the Bolund hill. Our measurements are determined in a boundary layer wind tunnel (WT) without stratification. Our results are compared with full scale (FS) ones. The FS results are obtained from the analysis of the database provided by RISO-DTU after the Bolund experiment. This experiment was conducted by them during a 3-month period in the winter of 2007-2008. Three component time resolved hotwire anemometry (3CHW) and two component particle image velocimetry (PIV) are used in our experiment in order to explore the dependence of the results on the experimental technique.
