Investigation of film cooling effectiveness and enhancement of cooling performance
, 2018 Advanced gas turbines are designed to operate at increasingly higher inlet temperatures to increase efficiency and specific power output. This increase in the operating temperature is enabled by advances in high-temperature resistant materials such as super alloys and thermal-barrier coatings (TBCs) and by the development of effective cooling methods ...

Flow visualization of film cooling with spanwise injection from a small array of holes and compound-angle injection from a large array [PDF]
Film injection from discrete holes in a smooth, flat plate was studied for two configurations: (1) spanwise injection through a four hole staggered array; and (2) compound angle injection through a 49 hole staggered array.

Influence of coolant tube curvature on film cooling effectiveness as detected by infrared imagery [PDF]
Thermal film cooling footprints observed by infrared imagery from straight, curved, and looped coolant tube geometries are compared. It was hypothesized that the differences in secondary flow and in the turbulence structure of flow through these three ...
