碩士 === 國立交通大學 === 機械工程系所 === 94 === Film-cooling is one of schemes to decrease heat load of a gas turbine blade. A finite volume scheme and high Reynolds K-E turbulent model are used to analyze the effects the stationary and moving blades on film-cooling process. The results show that the optimal positions of the holes of the cooling film are different between the blade under the stationary and moving situations. Then, in order to gain efficient film-cooling scheme the effect of the movement of the blades should be taken into consideration.
