Abstract
This report documents the results of numerical experiments investigated with the help of the computational fluid dynamics solver TRACE which were performed along the sidewall of a plane turbine cascade considering four film cooling configurations with slot ejection. In doing so, two configurations which have been experimentally examined
within two German research projects:
AG-Turbo Plattformk¨uhlung I + II
are adopted. Furthermore, the effect of a contoured slot taking the pressure distribution at the inlet region of the cascade sidewall into account is studied. The results are
analyzed with respect to film cooling effectiveness and the surface heat transfer. The results are mainly influenced by the three-dimensional flow structures visualized with
the stream-wise vorticity.
