摘要

Detailed experimental investigations were conducted of the detailed flow structures in a model two-stage low-pressure turbine. The objective of this study is to gain more insight into phenomena affecting flow behaviour due to the indexing airfoil effects in multi-stage machines. To investigate the effect of the vane clocking on axial turbine efficiency and performance, an analysis of the experimental results of the steady and unsteady flow measurements throughout the flow field for different circumferential positions of the first stator is performed. Detailed flow pictures were measured for all measuring planes according to the radial and circumferential inter-row traversing. Aerodynamic measurements were compared to the turbine design speed and "classical" clocking position of the two stators. Herein, some steady and unsteady flow measurement results, and the external characteristics for different circumferential positions of the stator vanes are described. The experimental investigations presented in this paper were carried out since mid-nineties on a 2-stage turbine research facility TM-3 at the Institute of Turbomachinery of Technical University of Lodz in close cooperation with Institute of Jet Propulsion and Turbomachinery of Technical University of Aachen, Germany.
