Abstract: This study investigated the effusion film cooling on a turbine leading edge model. The pressure-sensitive paint (PSP) technique was employed to analyze the film cooling effectiveness. Three different leading edge profiles ...

Abstract: The detailed Nusselt number distributions on leading and trailing endwalls together with the Fanning friction factors of a rotating two-pass parallelogram ribbed channel are simultaneously measured under forward and backward ...

Abstract: Effusion film cooling is effective for cooling high-temperature turbine blades because it requires less coolant and produces a more uniform temperature distribution than conventional film cooling. Effusion cooling for a ...
