Abstract: The effects of airfoil showerhead (SH) injection angle and filmcooling hole compound angle on nozzle endwall cooling (second order filmcooling effects, also called "phantom cooling") were experimentally investigated in a ...

Abstract: This paper presents the swirl purge flow on a platform and a modeled landbased turbine rotor blade suction surface. Pressuresensitive paint (PSP) mass transfer technique provides detailed filmcooling effectiveness distribution ...

Abstract: This paper experimentally investigates the effect of a turning vane in hub region on heat transfer in a multipass rectangular channel with ribroughed wall at high rotation numbers. The experimental data were taken in the ...

Abstract: Turbine vanes are typically assembled as a section containing single or double airfoil units in an annular pattern. First stage guide vane assembly results in two common mating interfaces: a gap between combustor and vane ...

Abstract: A multipassage internal cooling test model with a 180 deg U-bend at the hub was investigated. The flow is radially inward at the inlet passage while it is radially outward at the trailing edge passage. The aspect ratio ...
