At the Institute for Gas Turbines and Aerospace Propulsion, high-resolution computational fluid dynamics (CFD) simulations are performed to investigate the behaviour of high-pressure turbine stages under realistic operating conditions. The focus is on questions relating to aerothermal loading and the influencing factors of unsteady flow phenomena from the combustion chamber. Various methods and tools are currently used to analyse the extensive simulation data. However, in order to ensure uniform, reproducible and easily adaptable evaluation, Python-based routines for turbomachinery applications are to be developed as part of this work.

Fundamental investigations into flow phenomena and interaction mechanisms in modern high-pressure turbines are carried out at the Large Scale Turbine Rig (LSTR). The focus is on a Reynolds-scaled high-pressure turbine rotor, which was scaled using a Mach-like high-pressure turbine test rig. Reynolds scaling offers decisive advantages for experimental investigations, but does not reproduce Mach number effects.
