Numerical Study on Film-Cooling Effectiveness for Various Film-Cooling Hole Schemes
ASME-JSME-KSME 2011 Joint Fluids Engineering Conference: Volume 1, Symposia – Parts A, B, C, and D, 2011 Film-cooling has been widely used as the important alternative to protect the turbine blade. Since the film-cooling hole geometry is one of the most influential parameters for film-cooling performance, various film-cooling hole schemes have been developed to increase cooling performance for the past few decades.

Experimental study on a spray and falling-film cooling system
Case Studies in Thermal Engineering, 2021 After spraying, the cooling medium retains potential cooling capability and, consequently, can form a falling film to further cool the downward area. In this paper, the flow patterns and the heat transfer coefficients are correlated respectively in the ...

Cooling Characteristics of Film-Cooled Turbine Blades [PDF]
Volume 4: Heat Transfer; Electric Power, 1984 A series of experiments was performed to measure the cooling effectiveness of pin-fin type blades applicable to the first-stage blades of the high pressure turbine for the Advanced Gas Turbine of Japan (AGTJ-100A). Actual pin-fin type blades were used in three-dimensional hot cascade tests.
