Experimental and Numerical Investigation of Secondary Flow Structures in an Annular Low Pressure Turbine Cascade Under Periodic Wake Impact—Part 2: Numerical Results
Benjamin Winhart,Martin Sinkwitz,Andreas Schramm,David Engelmann,Francesca di Mare,Ronald Mailach +5 more
TL;DR: In this article, the results of the numerical investigations of periodic wake-secondary flow interaction carried out on a low pressure turbine (LPT) equipped with modified T106 profile blades were compared with measurements conducted in the same configuration and showed a good agreement.

TL;DR: In this paper, a 3D CFD model of an industrial steam turbine is developed, which consists of three parts: the nozzle groups covering only a portion of the annulus and the rotor of the impulse-type control stage, a cross-over channel directing the flow to a reduced diameter, and downstream reaction-type turbine stages.

TL;DR: In this article, the authors investigated the capability of the TT method to predict these phenom-ena by the example of the last two stages of a shrouded 4-stage air-turbine.
On the Periodically Unsteady Interaction of Wakes, Secondary Flow Development, and Boundary Layer Flow in An Annular Low-Pressure Turbine Cascade: An Experimental Investigation
TL;DR: In this paper, the impact of periodically unsteady wakes on the development of profile and end wall boundary layers and consequently on the secondary flow system was investigated on an annular 1.5-stage axial turbine rig at Ruhr-Universität Bochum's Chair of Thermal Turbomachines and Aeroengines.
