Abstract

This paper presents a variety of different numerical set-ups for the simulation of a straight turbine cascade ow. The DLR TRACE code was employed for the numerical investigations. Special emphasis is laid on the transition prediction applying the -Retransition model. The Re-transition model with diferent underlying turbulence models and turbulence model modifications are varied. The numerical investigations are compared to experimental data obtained at the Wind Tunnel for Straight Cascades at DLR, Göttingen. For comparison with the experimental data one exit Mach number at a low transonic region and two different incidence angles are investigated. For the measurement infrared imaging, Schlieren photography, pressure taps and hot-wire-anemometry are applied.
