The paper describes the experimental and numerical investigations of stator clocking
effects on performance of a two-stage impulse turbine with low-aspect ratio airfoils.
The data present the clocking effect that can be observed both for local flow patterns
and external characteristics for the entire turbine in terms of efficiency. Finding an
optimal relative circumferential position of stators in a multistage axial turbine has been
the subject of extensive investigations in the last decade.
