As part of this master thesis the inflow in the linear blade cascade wind tunnel of the Institute is measured by HWA (Hot Wire Anemometry). For this purpose, there are 9 x 28 measurement points about 10mm after the end of the upper and lower tongue with the one-dimensional measurement and 7 x 28 sampled data points in the three-dimensional measurement. The one-dimensional velocity measurements are used to determine the integral scale which put simply the diameter of flow vortices represent. In addition, the Reynolds stresses are calculated from the three-dimensional velocity measurements and evaluated using a so-called anisotropy invariant map. First of corresponding probe calibrations are performed to obtain accurate results later. The wind tunnel with the associated experimental setup, including measurement technique used is described in detail. The theory for the analysis and the calculation steps are also discussed.
