Abstract: This study shows that no additional measurement error due to unsteadiness was detected, when measuring in periodic turbomachinery flows at frequencies up to 5 kHz with steady, pneumatic probes. An experiment was designed, ...

Abstract: In this paper, the detailed steady and unsteady numerical investigations of a 1.5-stage axial flow turbine are conducted to determine the specific influence of interplatform steps in the first stator—as caused by deviations ...

Abstract: Since the experiment in turbulence research is of very high importance for evaluating turbulence hypothesis, turbulence measurements were carried out in a two-stage two-spool transonic turbine test rig at the Institute for ...

Abstract: In this paper, we present the evaluation of the aerodynamic robustness to rim seal purge flow of an optimized 1.5-stage axial turbine configuration with a bowed stator profile and endwall contouring. Performance maps ...
