Abstract: The present paper addresses the experimental and numerical study of the unsteady flow established in a high-pressure turbine stage with rim seal purge. The HPT test section, operated at engine-relevant flow conditions in ...

Abstract: Quantifying and predicting the effects of freestream turbulence on the aerodynamic performance of turbomachinery flows continues to be of primary interest to advance the physical understanding and modeling of loss mechanisms. ...

Abstract: Particle image velocimetry (PIV) measurements in the blade-to-blade (B2B) plane and cascade outlet plane (COP) of a high-speed low-pressure turbine (LPT) cascade were performed at engine-representative outlet Mach number ...

Abstract: This article presents the implementation of a particle image velocimetry (PIV) into the high-speed short-duration rotating turbine facility of the von Karman Institute. The advantage of PIV as a whole-field measurement is ...

Abstract: Qualitative and quantitative visualizations of transonic turbomachinery flows provide essential information on compressibility and Mach number effects on boundary layer development, shock-boundary layer interactions, and ...
