Film cooling blowing through several cooling hole geometry has been studied experimentally. The influence of hole geometry, mass flux ratio and main stream turbulence intensity and boundary layer thickness to the film cooling effectiveness has been investigated by using the low speed wind tunnel. The tests have been conducted by blowing heated air through film cooling holes keeping the main stream at room temperature. Significant improvement in film cooling effectiveness is attained by adopting the so called "fan shaped film cooling holes" in comparison with conventional circular hole geometry. In this paper, not only the film cooling effectiveness on the wall but also the detail distribution of the injected film jet downstream of the film cooling hole will be discussed.
