Matthias Teich
Kassel University, Germany


Matthias Teich is a mechanical engineer, graduated from University of Kassel in 2013. For his above-average academic achievements, he received a Junior-Scholarship and the award of "Best overall grade". Since 2013 he is a research assistant at the University of Kassel and is just about to complete his doctorate in the section of turbomachinery at the department of Thermal Power Engineering under the leadership of Univ.-Prof. Dr.-Ing. Martin Lawerenz. Teich has focused his dissertation on unsteady flow phenomena in a compressor stator cascade with hybrid numerical methods. The main research-topic is the Rotating Instability (RI), which is a self-induced flow instability at still stable operating conditions prior to Rotating Stall (RS). With his collegues Teich could recently show, that little differences at the inlet near the hub have a big impact on the development of rotating flow pattern, which are connected to the RI. Additionally, he found that the methods used in the simulation (URANS vs. (D)DES) seem to play a major role. He could identify a connection between secondary flow structures on the hub at the leading edge and the RI. For the exchange of experience and knowledge, Matthias Teich is a member of the "Verein Deutscher Ingenieure" (VDI) and the "Deutsche Luft- und Raumfahrt Gesellschaft" (DLRG).
