Detailed experimental investigations were conducted of flow structures in a model two-stage low-pressure turbine. The objective of this study was to gain more insight into phenomena affecting flow behaviour due to the indexing airfoils in multi-stage machines. To investigate the effect of the vane clocking on turbine efficiency an analysis of the experimental results throughout the flow field for different circumferential positions of the first stator was 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 nominal speed and design 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 [1] on a 2-stage turbine research facility TM-3 at the Institute of Turbomachinery of Technical University of Lodz.
