Untersuchung des Stroemungsverhaltens von hochbelasteten ungekuehlten Niederdruck-Turbinengittern unter Berucksichtigung der Rotor-Stator Interaktion (Examination of Flow Behavior of Highly Loaded Uncooled Low-Pressure Turbine Grids with Regard to Rotor-Stator Interaction)

Abstract

Tests are made on two highly loaded low-pressure turbine grids, which have been specially developed in order to make use of the positive effects of rotor-stator interaction, observing simultaneously the typical Mach and Reynolds number combinations. After an introduction on the influence of rotor-stator interaction on the profile border layers in turbo machines, a trial construction ensues in a High-Speed Grid Wind Canal (HSGWC), the dimensions and problematic areas of which are also described. The next two chapters compare the results of the experiment with the non-empirical, theoretical data. The last chapter contains recommendations on how one might outfit a low-pressure turbine grid with regard to periodically non- stationary afflux.
