Abstract

One of the most significant systems which play a crucial role in power plant for power production is the
Turbine. Turbine blade was revolve with the help of high temperature’s steam. The temperature of hot steam was far
above the permissible temperature of blade materials. Advanced cooling technologies must be applied to cool the blades,
so they can withstand the extreme conditions. Film cooling is mostly used in high temperature and high pressure blades
as good cooling effect. In this study, the film cooling cogency in different regions of gas turbine blades was investigated
with diversified film hole / slot shapes and mainstream flow situation. The study consisted of four parts:1) effect of
upstream wake on blade surface cooling, 2) effect of upstream vortex on platform purge flow cooling, 3) influence of hole
shape and angle on leading edge film cooling and 4) slot film cooling on trailing edge. Pressure sensitive paint (PSP)
technique was used to get the conduction-free film cooling effectiveness distribution.
