Task

According to the current state of research, it is not yet possible to quantitatively determine wall shear stress distributions (magnitude and direction) with low measurement uncertainty. For this reason, the liquid crystal technique is being further developed at the Institute of Thermal Turbomachinery (ITS).

Thesis Focus: For the upcoming measurement campaign, flow data have to be acquired highly resolved in space. As part of your thesis, you will take part in all steps of the data acquisition, starting from the selection of a suitable boundary layer probe all the way through to the actual data acquisition as well as processing and post-processing of the data. The scientific focus of your thesis will be the analysis of local wall shear stresses to provide data for calibration. You will familiarize yourself with the measurement technique using the liquid crystal test rig, gain insides into flow measurement techniques and compare the data with in-house numerical data as well as literature.

Curious? Skills in Python language and sound basics in aerodynamics and optics are very welcome but not required. The thesis can be completed in German or English starting any time from now.
