The main objective of this thesis is the inflow measurement of the linear blade cascade wind tunnel at the institute by HWA (Hot Wire Anemometry). The measuring cradle contains a field of 7 x 28 measuring points which will be sampled. There will be carried out experiments and evaluation of 1D- and 3D-measurements. The structure of the measurement system and its components are discussed in detail. The velocity calibration of both hot wire probes is performed as well as a directional calibration of the 3D-probe.
Apart from the speed measurement and analysis of the velocity data, the Reynolds Normal Stresses and the Reynolds Shear Stresses are determined, which are subsequently essential for the evaluation of the flow field. Special attention is put on the graphical representations and the visualization of the secondary flow field. The turbulence intensities of the measured cross section can be determined and there will be given the possible causes for the anisotropy of the flow field.
