The objective of this study was 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 has been performed. Aerodynamic measurements were compared to the turbine design speed and to the classical clocking position of the two stators [1].
