Abstract

This paper presents a comparison of the experimental results for a flush slot at two angles of inclination. The experimental investigation of heat transfer with film cooling near injection slots were carried out in a wind tunnel. The secondary flow was injection with two angles; 35 and 90 deg to the mainstream flow direction. The experimental objectives were to determine, for each inclination angle, the influences on the film cooling effectiveness and on heat transfer coefficient. Injection through slots gives better results for film cooling compared with that of injection through holes.
