...S. C. Lau; J. Cervantes; J. C. Han; R. J. Rudolph Naphthalene sublimation experiments were conducted to study heat transfer for flow through blockages with holes in an internal cooling passage near the trailing edge of a gas turbine airfoil. The cooling passage was modeled as two rectangular...

... the cooling air through the grooves to protect the trailing edge surface. In this study, naphthalene sublimation technique was used to measure area averaged mass/heat transfer coefficients downstream of the breakout plane on the slot and on the land surfaces. Three slot geometries were tested: (a) a baseline...

... ratio ( e ∕ D h ) is 0.055. The tests were conducted at various rotation numbers (0, 0.2, 0.4), while the Reynolds number and the rate of bleed flow to main flow were fixed at 10,000 and 10%, respectively. A naphthalene sublimation method was employed to determine the detailed local heat transfer...

...P. Jin; R. J. Goldstein Local mass transfer measurements on a simulated high-pressure turbine blade are conducted in a linear cascade with tip clearance, using a naphthalene sublimation technique. The effects of tip clearance (0.86–6.90% of chord) are investigated at an exit Reynolds number of 5.8...

...M. Papa; R. J. Goldstein, Mem. ASME; F. Gori An experimental investigation has been performed to measure average and local mass transfer coefficients on the tip of a gas turbine blade using the naphthalene sublimation technique. The heat/mass transfer analogy can be applied to obtain heat transfer...

...Hyung Hee Cho; Seung Goo Kang; Dong Ho Rhee An experimental study has been conducted to investigate the heat/mass transfer characteristics within film cooling holes of square and rectangular cross section. The experiments for this study have been performed using a naphthalene sublimation method...
