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

Abstract

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 RISØ-DTU after the Bolund experiment. This experiment was conducted by them during a 3-month period in the winter of 2007-2008 [1]. Three component time resolved hotwire anemometry (3CHW) and two component particle image velocimetry (PIV) are used in our experiment
