Abstract: Efficiency is an essential metric for assessing turbine performance. Modern turbines rely heavily on numerical computational fluid dynamics (CFD) tools for design improvement. With more compact turbines leading to lower ...

Abstract: For novel high-speed small core turbines, with tip clearance below 0.5 mm, even small blade-to-blade tip clearance variation is significant. The assessment of these complex flows is pertinent to the design of the next ...

Abstract: Optical measurements based on fast response pressure sensitive paint (PSP) provide enhanced spatial resolution of the pressure field. This paper presents laser lifetime PSP at 20 kHz, with precise calibrations, and results ...

Abstract: Particle image velocimetry (PIV) is a well-established technique for determining the flow direction and velocity magnitude of complex flows. This paper presents a methodology for executing this nonintrusive measurement ...
